An 18-year-old man has been arrested on suspicion of affray after supermarket staff were threatened with a crowbar.

The incident happened at Morrisons on Clipbush Lane, Fakenham shortly before 5pm on Tuesday, April 23.

Police then attended a traveller site on George Edwards Road to make the arrest and a group was ordered to leave.

It is thought that the suspect left Morrisons in a white Hyundai and inquiries led officers to arrest the man at the unauthorised traveller encampment.

Ben Clarke, duty manager at the store, was there at the time of the incident and said: 'The safety of our staff and our customers is absolutely paramount to us. That is always our focus.'

The man was taken to King's Lynn Police Investigation Centre where he remains in custody.

Following the arrest, officers served a Section 61 notice on the encampment ordering the group to leave.

The private land owner has previously asked the group to leave, which they refused to do.

A number of police resources attended, including the dog and drone units, and the four vehicles and three caravans left the site at 9.30pm.

This isn't the first time police have been called after an incident at Morrisons in Fakenham.

In a separate incident in January earlier this year, police were called to investigate reports of a man touching himself inappropriately and following a woman and her son around the supermarket.

Back in 2016, masked robbers forced staff to open tills and escaped with cash in another separate incident.

Police are keen to hear from anyone who may have witnessed the incident at Morrisons on Tuesday, April 23 between 4.40pm and 5pm or may have dash cam evidence.

Police are also keen to hear from anyone who may have seen a white Hyundai travelling in the area at the time.

Anyone with information should contact PC Caroline Fish at King's Lynn Custody Investigation Unit on 101 quoting CAD reference 344 of 23 April.
