Two men threatened restaurant staff with a knife before escaping with cash.

The men walked into the Upper Crust restaurant in Warwick at 8.45 p.m. on Thursday when three members of staff were working.

The suspects went to the cash register and removed some cash. At this point staff members were alerted to the robbery and came out of the kitchen to confront the men, but they were threatened by one of the men brandishing a knife.

One of the suspects is described as about 5ft 9in, slim build, wearing a loose grey top. The other is described as being 5ft and also of slim build.

Police are appealing for any witnesses or anyone with any information to contact the Somerset Criminal Investigation Unit on 234 1010.
