The Major Crimes Unit of the Royal Newfoundland Constabulary is investigating an armed robbery at a gas station in the west end of St. John's Saturday morning.

RNC officers were called out at 3:42 a.m. to a station in the city's west end.

A lone male reportedly entered the store, and was armed with a weapon. He then demanded cash and fled the scene with an undisclosed amount of money.

It's not known what type of weapon was used or if there were any injuries.
