An estimated $7,000 in cash was taken from the Haagen Dazs ice cream shop in Maraval last night.
Reports are that around 9:30pm, an armed man entered the store pretending to be a customer and walked up to the cashier.
The man then raised his jersey, showing a gun and announced a holdup.
The bandit proceeded to relieve the workers of their personal cash and valuables, along with the cash from the cash register and a deposit bag in the storage room.
The suspect then escaped.
St Clair police are investigating
