Toronto police have released surveillance camera images of a male suspect after a 14-year-old girl was sexually assaulted while studying in the library at Fairview Mall on Monday afternoon.

Police were called to the Toronto Public Library at Fairview Mall, at Don Mills Road and Fairview Mall Drive, at 3:06 p.m.

Investigators say a girl was studying at library when a man sat down next to her and began talking to her.

The girl was allegedly sexually assaulted by the man.

Police say the girl then left the library and the suspect followed her out. The girl later returned to the library to contact police.

The suspect is described as a man in his mid-20s, standing six-feet-tall, with a slim build. He had short light-brown hair and a receding hairline with sideburns but was otherwise clean shaven.

He was last seen wearing brown lens sunglasses, a lime green t-shirt, blue jeans and grey shoes with white soles and laces. He was carrying a rectangular leather bag with a handle.

Anyone with information is asked to contact police at 416-808-3300, or Crime Stoppers at 416-222-8477 (TIPS).
