The police were knocking on his door.
Desperate to destroy evidence, the suspected pimp threw a computer and several documents out the window of his sixth storey flat at Block 212, Ang Mo Kio Avenue 3.
Police officers had to saw through the 3-room flat's front gate and break the lock before they were able to arrest the 35-year-old man.
The arrest on Wednesday at about 8pm was part of a six-hour operation at Ang Mo Kio, Jelapang Road, Mergui Road and Rangoon Road.
The raids were targeted against an online vice syndicate.
Several plainclothes police officers were seen photographing evidence - pieces of the smashed computer, keys and polyfoam bags - scattered at the grass field at the block, reported Chinese evening daily Lianhe Wanbao.
The raid on the flat in Ang Mo Kio lasted three hours, during which police officers confiscated eight bags worth of notebooks, mobile phones and money.
The notebooks and phones are believed to contain important information regarding the vice syndicate.
Residents told Lianhe Wanbao that they heard a loud sound at around 8pm, most likely from the impact of computer hitting the ground.
