An extensive police investigation was underway in northeast Edmonton on Wednesday night, in relation to an "ongoing missing persons investigation," officers said.

The RCMP issued a plea for help from the public Saturday evening as they try to find the person who pinched the buttocks of a young girl while walking past her in Stony Plain on Friday.

Police have located and spoken with a man whom they believe may have information that could help them with their investigation into a homicide in northeast Edmonton last month.
