There's another prowler on the loose in Hamilton, this time on the east Mountain.

Police say the prowler peered into the bedroom window of a woman in her twenties. It happened on East 35th Street around 11:30 p.m. Sunday.

The woman was awake in her bedroom but didn't notice. A neighbour did, however, and went outside to confront the man. He tried to restrain him until police arrived, but the prowler broke free.

The culprit may have a cut on his face from the struggle, police say. The neighbour wasn't injured.

Police searched the area but couldn't find a suspect.
