A convenience store in Corner Brook was robbed of cigarettes and one case of beer, in an armed robbery Thursday afternoon by a thief who said he was sorry.

The owner of Mathews Mini-Mart and Laundromat, Carmelita Mathews, told CBC News a man, wielding a knife, entered the store on Humber Road and demanded cash.

The 24-year-old female clerk, who was just recently hired, called police and the robber walked away with just cigarettes and a single case of beer.

The owner said the robber apologized before holding up the store.

He was seen heading west on Humber Road. However, no description of the car was given.

The Royal Newfoundland Constabulary was called to the store around 4:20 p.m., said Sgt. Robert Edwards.

"The male is described as being in his early 20s ... 23- or 24-years-old," Edwards said.

"Approximately 5 foot 6 in height, slim build with short brown hair."

The employee who was working at the time is speaking with police, and the RNC is asking for the public's help in identifying the robber.
