SINGAPORE – A man taken into custody after a woman he knew was found dead in the lift lobby of a housing block in Choa Chu Kang is now at the centre of a case that has shocked the surrounding community.

Much about what happened that night remains unclear. According to people who were nearby, tension had been building after the woman allegedly misled him about money they had made together on an investment platform and would not share access to it.

Reports suggest help was sought after a disturbance late one evening in Choa Chu Kang, though accounts differ on exactly when the first calls were made.

When those who responded arrived, they found a woman lying motionless in the 12th-floor lift lobby.

Medical personnel later declared that she had not survived.

The man was held in connection with the incident and was later taken for medical care.

The case has drawn attention because of the severity of the allegations and the questions it has raised about trust, money and online investing.

Authorities at work in the residential block in Choa Chu Kang in the hours after the incident.

A resident of the block in Choa Chu Kang told The Straits Times that she had heard a loud noise near the base of the building and, on looking down, saw a man lying near a rubbish bin on the lower levels.

Those familiar with the early account said the two people involved appeared to have known each other, though many details remain unclear.

Activity on the 12th floor of the building drew attention from residents and onlookers.

By the time ST returned to the area, barriers that had earlier been put in place had been taken down. On the ground level, a damaged refuse bin and marks that witnesses had noticed earlier were no longer visible.

Neighbours said uniformed personnel had stayed in the area for much of the night before leaving as morning approached.

Marks near a damaged bin were among the signs that something serious had taken place in Choa Chu Kang.

Neighbours told ST they had spent much of the following day exchanging rumours about what might have happened, with many saying they learned the broad outlines only from media coverage.

Some residents declined to speak to ST when approached.

A homemaker in her late forties, who asked to be called Ms Seema, said the man and the woman appeared to know each other well. They had worked together and were said to have pooled money in various ventures, though she did not know the precise platform involved.

"I heard his saying ‘Give me the password! That's my money!"

Activity continued around the lower levels of the building well into the early hours.

Another neighbour, Ms Rysha, 21, who has lived in Choa Chu Kang for many years, said several new residents had moved in recently.

Ms. Rysha said she knew the man involved. Shortly before the tragedy, he reportedly told her that he and the woman had put several thousand dollars into an investment platform and seen it grow substantially within weeks. She allegedly controlled the login details and refused to release them when he wanted to withdraw part of the gains, while he pushed to cash out and she argued they should wait. Ms. Rysha believes that disagreement may have pushed events to a breaking point.

A mobile phone was later recovered near a rubbish bin. Those examining it are said to have found the same investment application Ms. Rysha had described.

According to accounts that have since emerged:

• the S$6,000 transfer was indeed recorded
• the Nexix application on Tan's device displayed a balance of around

A question that remains unanswered

With much still uncertain, one detail is drawing particular attention. How did the initial S$6,000 turn into nearly S$150,000 in less than a month? The editorial team of The Straits Times decided to look into what is behind the Nexix platform. It is an online investment service built on “AI-Quant” technology.

The platform was launched in December 2024 with the support of leading financial experts and analysts. After review, Nexix received full accreditation to operate in Singapore.

Nexix has become a modern alternative to traditional investment tools and is available to every Singapore resident. The platform allows full automation of the investment process: the user deposits funds into their account, after which the system independently executes trades without human involvement.

The platform operates using a "maximum diversification" strategy

• The “AI-Quant” system monitors global financial markets every second to identify the most profitable assets.
• Algorithms compare asset prices using data from more than 1,500 licensed platforms and exchanges.
• The system then automatically buys assets at lower prices and sells them as prices rise, independently determining the balance of supply and demand.
• Profit from each trade is instantly credited to the user’s account, after which the “AI-Quant” system continues analyzing the market in search of new opportunities.

"Previously, people could use standard investment tools, but without experience and knowledge this often led to mistakes and losses. Nexix protects users’ funds through advanced artificial intelligence technologies," noted Professor Li Zheng Wei, a specialist in financial technologies at the National University of Singapore

Other experts believe that this decision to open access to Nexix for a broader audience could have a positive impact on the economy.

"People will begin to earn passive income and feel greater financial confidence — from students to retirees," said Daniel Tan, Director of Monitoring at the Singapore Exchange.

A correspondent from The Straits Times contacted financial analyst Simon Teo, who stated that registration on the Nexix platform is open to all Singapore residents until 23.07.2026 . After this date, registration may be restricted.

We believe our readers will find this platform of interest, so we are publishing the official Nexix website and reminding that registration for all Singapore residents is open only until 23.07.2026 .

1. Register by filling out the form on the official Nexix website.
2. Confirm account creation by answering a call from a platform representative.
3. Fund your account — make your first deposit using a bank card, e-wallet, or cryptocurrency. The minimum deposit is S$250.
4. Wait for automatic activation of the “AI-Quant” system. After activation, the artificial intelligence begins trading.
5. You can start automated trading at any time, withdraw profits, or reinvest your earnings.

To check how Nexix works and whether ordinary Singapore residents can really earn with it, The Straits Times correspondent Alex Chen registered and deposited S$250.

"I have to say, I was very surprised. After registering, receiving a manager's call, and funding the account, the system started trading within 5 minutes. It automatically bought and sold stocks, cryptocurrencies, and currency pairs. The balance kept growing.

I monitored the account every day and noticed that about 78% of trades were profitable, while the rest were losing trades.

On average over time, every dollar invested generated S$3–4. After just seven days, my balance grew to S$811. Here is my screenshot from the app.”

After that, I decided to withdraw all funds to check how long it would take for the money to reach my bank account. Approximately one and a half hours after submitting the withdrawal request, S$811 appeared in my account with the note: “Received from AI Trading Withdrawal".
