Hamilton police looking for alleged violent offender

Hamilton police are asking for the public's help in finding a man wanted for several violent offences.

An arrest warrant has been issued for 19-year-old Rory Costello of Hamilton.

Since September,  police say they were provided  with  information regarding several incidents involving Costello.

Police say Costello knows there is a warrant out for his arrest, and has been "actively evading" officers since September of last year.

Costello is facing several charges including two counts of  assault with a weapon, sexual assault and uttering threats.

Police believe the incidents were targeted, but they're asking the public not to approach him directly and instead call 911 immediately.

Police are not releasing further details in order to protect other parties involved.
