Police are after a "short, tubby" middle-aged man who indecently assaulted a teenage girl near a Christchurch school today.

Police said at about 11.15am, the 14-year-old was walking outside St Martins School when she noticed an Indian man get out of his car.

He approached her, asking for an address in Glenelg Spur, in the suburb of Hillsborough.

The teen didn't know the address and apologised to the man, who then hugged her and grabbed her bottom.
