Residents of the Chapman Mills neighbourhood in Barrhaven are being warned about a series of suspicious incidents involving a lone man.

Since June 2, police have received three separate reports of a man looking into basement windows.

"Residents are asked to report any suspicious activity they observe to police without delay," police said in a media release issued Friday.

Police do not have a description of the man, though.

Anyone with information is asked to call the Ottawa police sexual assault and child abuse unit at 613-236-1222, ext. 5944, or Crime Stoppers at 613-233-8477.
