A video that went viral showing a 12-year-old girl kneeling and being slapped in the face about 20 times by a group of teenagers in broad daylight on the rooftop of a Hong Kong building has sparked a citywide police search for the attackers.

Detectives from the Tsuen Wan criminal investigation unit began looking into the assault after the victim’s father made a report to police at 6.43pm on Sunday.
