Police are investigating two overnight robberies in Conception Bay South.

An armed man tried to hold up a convenience store in the Foxtrap area shortly after 9:40 p.m. Thursday. 

However, he left the scene empty-handed. 

Around 2:30 a.m. Friday, a man held up a gas bar in Kelligrews. This time, the robber got away with cash, although police did not reveal how much. 

Police are not releasing any other details, including the weapons that were used, but said the robberies do appear to be connected.
