Hamilton police have charged a man with multiple accounts of sexual assault and say they believe there are more victims out there.

Police say a woman approached them in November last year saying she had been sexually assaulted back in July of 2016.

During their investigation, two more women came forward and said they had been sexually assaulted by the same man, between July and November of 2016.

Michael Glen Harris, 53, is now facing seven charges of sexual assault, seven charges of forcible confinement, five counts of assault, assault with a weapon, uttering threats, and theft under $5,000.

Police say there are multiple charges because some of the victims were assaulted more than once.

Investigators say the women were all known to Harris.

Anyone with information is asked to call the sexual assault unit at 905-546-8958
