Three people are in custody, following a robbery at a filling station in Cork City last night.

Two masked men armed with knives held up staff at a service station on Leitrim Street and stole a quantity of cash, just before half eight.

The men left the scene in a car, which was driven by another man and had a female passenger.

A garda car patrolling in the area stopped the car and arrested a woman and two men, ranging in ages from late 20s to mid 40s.

Another man escaped on foot.

Gardaí recovered knives, balaclavas and cash in the car.
