The body of a hiker, who went missing last Friday, is believed to have been found yesterday evening on the top level of a multi-storey carpark at Block 468A, Segar Road, in the Bukit Panjang neighbourhood.

The police, in a statement yesterday night, said the 27-year-old man was pronounced dead by paramedics at the scene. They have classified the case as unnatural death and investigations are ongoing.

On Sunday, a search party, including 60 volunteers, combed nature areas and parks for clues of Mr Steward Lee's whereabouts. The avid hiker left his home in Bukit Panjang alone, presumably for a hike, at 2pm last Friday and did not take his mobile phone with him.

He was last seen at Block 407, Fajar Road, in the Bukit Panjang neighbourhood at around 2pm on Friday.

He was wearing a black T-shirt and jeans. When he did not return, his family made a police report on Friday night. The next day, the police put an appeal on their Facebook page.

His sister, Ms Lee Yunqin, 29, a researcher, also posted a request on her Facebook page for volunteers to conduct a sweep of nature areas. The volunteers combed popular hiking areas, including the Bukit Timah Nature Reserve, Dairy Farm and Singapore quarry area, Mandai, Zhenghua Park and the rail corridor.

A group of friends and family members also went searching for him in the Bukit Panjang neighbourhood.

Speaking to The Straits Times on Sunday, Ms Lee said her brother went hiking almost every day and this was the first time he had gone missing.

She added that Mr Lee, who is unemployed, would always inform his family if he was staying out.

Ms Lee could not be contacted last night but it is understood that the police have informed her about the body that was found yesterday evening.
