SINGAPORE - A secondary school student collapsed in school and died on Wednesday (Feb 15) afternoon.

The Singapore Civil Defence Force (SCDF) said it was alerted to a call for an ambulance at about 4.40pm.

An unconscious teenager at Loyang Secondary School was taken to Changi General Hospital. He later died.

Bryan Chee, 15, was an active student who loved basketball, Lianhe Wanbao reported.

His father told the Chinese evening daily that his son had a congenital heart defect and went for regular check ups. He was otherwise healthy and fit, he said.

His aunt, Agnes Tan, wrote a heartfelt post on Facebook remembering Bryan.

"I still cannot accept cannot believe what has happened to our family today. It came too fast, too tough, too pained for us to accept it. Someone dear to me who I watched him grow from an infant to a young handsome chap just left us today out of a sudden," she said.

She continued in Chinese: "I can't face this reality. Can't hear his voice, calling me 'third auntie'. My heart is aching."

The Straits Times has contacted Loyang Secondary for more details.
