A police helicopter was scrambled to help search for an armed robber after an attack on a forecourt in Norfolk.

Police were called to Nun’s Bridges Service Station, Thetford, at about 8.23pm on Tuesday, October 15, after reports that a man with a knife had demanded money from a cashier.

The offender fled the scene on foot with an undisclosed amount of cash taken from the till.

He is described as white, in his 30s, about five foot six inches tall, with dark hair and was wearing a chequered tea towel or similar over his face. It is thought he was also wearing dark coloured trousers and a dark coloured jacket and had with him a carrier bag.

The police helicopter was deployed to assist in an unsuccessful search for the offender.

Steve Jones, owner of the Harvest Energy service station, said no-one was injured during the incident, and the site reopened for business the following morning.

The site was in the news earlier this year when a police officer tried to sue Jones after falling over during a call-out, although she later withdrew the claim.

Officers are keen to hear from anyone with any information relating to the robbery. Witnesses should contact Norfolk Constabulary on 101 or Crimestoppers anonymously on 0800 555111.
