A middle-aged couple suffered multiple injuries after being attacked by three youths in an attack in Northampton.
The couple left at party at Russet Drive in Little Billing in the town just after 0001 BST on Saturday when they were approached by the gang who asked for a cigarette.
When the 57-year-old man said he did not smoke he was thumped in the face and pushed to the ground where he was kicked repeatedly.
The three then attacked the 44-year-old woman.

They stopped when they were disturbed by a neighbour looking out of his window.
The couple were treated in Northampton General Hospital.
