The pump well is about 12m deep with a diameter of 1.8m. At the time of the incident, the water level in the well was about 1m from the opening. However, Cpl Kok, who is a Malaysian national and Singapore permanent resident, did not resurface. A number of SCDF personnel jumped into the pump well to find him, but were unsuccessful. He was eventually pulled out of the well after the water was drained. Two SCDF regular personnel were arrested on Monday after preliminary investigations. The duo, holding the rank of Warrant Officer 1 and Staff Sergeant, were Cpl Kok's colleagues who worked in the same shift duty at the station. Speaking briefly to the media on Monday afternoon, Home Affairs and Law Minister K. Shanmugam said that from the facts so far, it was clear the conduct of some involved in the incident was "quite wrong". "It's in clear violation of SCDF's rules. It should not have happened. Unacceptable. Period." He added: "We will get to the bottom of it."
