CHENNAI: Police on Tuesday arrested Joshua of Mandaveli (45) for sexually harassing a college student returning to her hostel in Tiruvanmiyur a day ago.

However, Joshua fled the scene before help arrived. She filed a complaint with the Tiruvanmiyur police, who perused the CCTV footage in the neighbourhood and zeroed in on Joshua, and arrested him.

Investigations revealed that he was a car driver and riding back home after work when he molested her. Joshua was booked, arrested under Section 4 of the TN Prohibition of Harassment of Women Act, and remanded to judicial custody.
