Former civil defence chief Peter Lim Sin Pang has been granted early release from his six-month jail term.
The Singapore Prison Service, responding to queries from The Sunday Times, confirmed that he was released from the Prison Service's custody on Saturday.
Chinese evening paper Shin Min Daily News reported on Saturday that he was driven to the Selarang Park Community Supervision Centre in the morning, accompanied by a woman.
He was there to have his electronic monitoring device removed.
Mr Lim was found guilty in May of corruptly obtaining sex from a 49-year-old sales director who had worked for Nimrod Engineering, a vendor of the Singapore Civil Defence Force (SCDF).
This was in exchange for furthering the business interests of Nimrod. He also admitted to seven more corruption charges involving trysts with two other women who were working for separate vendors of the SCDF.
The 53-year-old started serving his sentence on June 26. He was placed on home detention from Sept 27, during which he was subject to electronic monitoring and curfew hours.
The former SCDF chief, who is married with a daughter, has since been dismissed from public service.
