A theft of guns from a vehicle on a restaurant parking lot turned a celebration into a worry for a Labrador man. 

Mike Ash was having dinner at Don Cherry's Sports Grill in St. John's on Wednesday night, when someone broke out a window of his rental vehicle.

Ash and his daughter were celebrating good news at the restaurant. 

"She found out she's cancer-free and doesn't have to come back for six months. Very good news," said Ash. 

In addition to a number of Christmas gifts, three shotguns and a rifle were taken from the vehicle.  

Ash is concerned that the guns could be used to kill or seriously injure someone.

"My biggest concern was public safety, obviously. We contacted the Royal Newfoundland Constabulary immediately, and filed a report to inform them that there was four firearms in the public," he said.

Ash said his father had given him the hunting weapons to bring back home to Happy Valley-Goose Bay.

"There was three 12-gauge shotguns and a .22-calibre rifle."

Ash told CBC News that the guns were stored in locked cases in the back of his vehicle.

"We were only here for a couple of days for doctor's appointments. I was getting ready to take them back on the plane to Goose Bay," Ash said.

"No one in St. John's knew I had them. I don't want to be responsible for having firearms [out] in the public."

Ash said there was no ammunition in the vehicle, but he's worried that whoever stole the guns will eventually get their hands on some.
