The suspects have then used the car to reverse into a shop front in Shaftesbury Avenue and attempted to steal a till from inside.
The same Fiesta has then been involved in a road traffic collision in Northumberland Crescent before the suspects left the scene.
Both suspects were wearing dark hooded tops.
The car has been recovered and enquiries are ongoing.
