SINGAPORE - A man in jogging attire was found dead at a park near the junction of Tampines Avenue 9 and 12 on Thursday (Feb 16) morning.

Police said the 59-year-old man was found lying motionless and was pronounced dead by paramedics at the scene.

The Straits Times understands that there were no signs of injury.

Police are investigating the case as an unnatural death.

The body was taken away at about 10.50am, and the police cordons have been removed.

Retiree Francis Tan, 64, who was cycling past Tampines Eco Green park at about 8am, said that the man appeared to be in his 40s.

"There were about five or six people with me, who gathered on the other side of the canal. We were wondering what happened. I saw the police officers take a few pictures of the body," said Mr Tan, who has been living in Tampines for about 20 years.

He added that it is the first time that he has seen such an incident happen in the neighbourhood.

A 56-year-old quality inspector, who wanted to be known only as Mr Lee, said that his wife was exercising at the park around 7am when she saw two police officers there.

Mr Lee was at the park at about 8am and noticed that the man had a bigger-than-average build.

"Not many people exercise around this area of the park early in the morning. He could be warming down after his exercise,"he said.
