A teenage girl was sexually assaulted while walking home from school in Melbourne's western suburbs earlier this year.

Police say the 17-year-old Point Cook girl was walking home about 5.30pm on February 28 when she was approached from behind by a boy on a bike, who sexually assaulted her before riding off.

Investigators on Tuesday released CCTV images of a teenage boy they want to talk to about the incident.
