Officers say that on Monday, a woman reported being approached in a parkade by a man who had his pants down.
RCMP say the woman became angry and swung her purse at the man before walking away.
About an hour later, another woman reported someone knocked on her door and that when she answered, a man with his pants down was standing there and she slammed the door on his face.
Police say that on Wednesday, a man matching the same description approached a woman walking outside and made a suggestive comment.
Const. Gary O'Brien says it appears the same man, in his 20s, is responsible for at least two of the incidents.
