Police in the UK are searching for an Irish teenage girl after she slapped a shop worker across the face with a large fish earlier this month.

CCTV images of a man and a woman have been issued after the worker was slapped across the face with a large bream in an Accrington supermarket on 4 February.

In a statement, police said: "The 52-year-old victim was working behind the fish counter when a young woman has approached the stall to ask about different fish.

"Without warning, the woman has picked up a large bream from the fish stall and slapped the worker across the face before running out of the store.

"The victim believes the incident was being filmed on a mobile phone by a man stood nearby who also ran from the scene when challenged.

"The girl is described as being Irish and aged between 15 and 18 with blonde, shoulder-length untidy hair.

"She was wearing dark jeans and a blue coat with white cuffs, white down the front and a red collar with ‘I love PB’ on the left breast pocket.

"The man is described as being around the same age, 5'8" tall, wearing a dark coat and dark grey trousers and boots."
