He rammed his moped into the front of the convenience store and managed to get in.

He waved a weapon that police believe was a black handgun at staff, telling them to open the safe and the tills before fleeing with cash and cheques.

It isn't yet clear how much cash was stolen.

The robber was male but wearing a full face black crash helmet and dark clothes so there is no further description.

The moped was dark coloured and had L plates, but the registration was hidden by a black bag.

Fortunately no one was injured but staff have been left shaken.
