An armed standoff in Stoney Creek Tuesday has led to the arrest of a man – already wanted by police in Alberta – on ten charges, including forcible confinement and pointing a gun at police officers.

Hamilton Police responded to a weapon-sighting incident at an address near Mountain Ave. S. and Maple Avenue in Stoney Creek on Tuesday, just after 11 a.m., where they were confronted by a man waving a handgun.

The gun forced an immediate withdrawal by officers, who quickly established a containment perimeter to manage the situation; closing off roads and advising residents to remain within their homes until the situation was deemed safe.

After a short standoff the occupants of the residence, 45 year-old Sean David Thorburn and a woman subsequently identified as a victim in the incident, exited without incident.

Thorburn has been charged with forcible confinement, five gun-related charges, possession of stolen property and probation violations.

The woman was released unconditionally.

Further investigation found Thorburn is wanted by both Medicine Hat Police Service and the RCMP.

During the search inside the residence police discovered a loaded .22 caliber handgun with four bullets in the magazine. Police also discovered  the vehicle parked in the driveway, a white Ford F550, had been reported stolen from the Guelph area. Subsequent search of the vehicle led to the finding of a stun gun.

Police then located and arrested 38 year-old Justin Mattina of Hamilton, who was believed to have been present in the home before police arrived.

Mattina has been charged with three counts of fail to comply.

Any information that could assist police with the investigation should be forwarded to Detective Sergeant Candace Culp at (905) 546-2907. Anonymous tips can be provided to Crime Stoppers at 1-800-222-8477 or online at
