Niagara Regional Police are investigating after 21 handguns were stolen from a Fonthill gun shop.

According to police, a man broke into the NAS Guns and Ammo around 10:30 p.m. Wednesday. The thief used a grinder for half hour to cut through the metal bars that line the windowxs.

Once inside he broke into several containers containing handguns and took 21 guns before taking off in a white or grey racing-style motorcycle.

All of the handguns were secured with trigger locking devices and no ammunition was stolen.

The stolen firearms are valued at $20,000.

Police are interested in speaking with witnesses.

They say there was significant traffic in the area at the time and someone would likely have seen the break-in.

Anyone with information is asked to call police at (905) 688-4111 ext 3300.
