Singapore Police fatally shot a man and detained two others early on Sunday near the Shangri-La hotel, where the Asia Security Summit is held, police said in a statement.
The incident took place at 4:36 a.m. local time on Sunday (20:36 GMT, Saturday) when a group of three people refused to open the car for check, according to the statement published on the official Facebook page of Singapore police.
The driver accelerated the car and crashed through police barricades, refusing to stop.
One of the detained possessed substance believed to be drugs, police said. Singapore has among the toughest anti-drug laws in the world, with possession of large quantities of narcotics carrying a mandatory death sentence.
The 14th Shangri-La Dialogue, also known as the Asia Security Summit, is held in Singapore between May 29 and May 31. The conference has been organized annually since 2002 to bolster security cooperation in the Asia-Pacific region.
