A peeping-tom who was caught on camera naked and doing indecent act on himself while watching a girl in a house in Pandan Indah has been detained by the police.

The obscene act by the 19-year-old man, who is a college student, was recorded on a closed-circuit television camera (CCTV) at the girl's house and the recording became viral after it was uploaded on the social websites last Saturday.

Ampang district police chief ACP Khairuldin Saad said investigations revealed that the man, who was arrested at 10.30 pm yesterday, was from the same neighbourhood.

He told Bernama that the suspect would be detained for investigation under Section 377D of the Penal Code.
