A man suffered a serious head injury after being knocked out by another man who was carrying an umbrella on a rainless night in Leeds.
The 20-year-old victim was assaulted in Woodhouse Lane, near to the junction with Rossington Street, shortly after 2am on Sunday.
A West Yorkshire Police spokesman said: “He had been on a night out with two female friends when he was attacked after he exchanged words with the man carrying an umbrella.
“He was punched once in the face causing him to fall and bang his head leaving him unconscious.”
He was taken to Leeds General Infirmary for emergency treatment.
His injuries were found to be serious but not life-threatening and he was kept in for observations.
The man who punched him was white, in his early twenties, 5ft 6ins to 5ft 8ins tall, with short, blond hair which was spikey on top.
He was wearing a short-sleeved polo shirt and blue jeans and was carrying a blue or green umbrella, which he had open despite it being dry. He ran off towards Albion Street.
Anyone who witnessed the incident or knows the identity of the suspect is asked to contact City and Holbeck CID via the non-emergency number 101 or call Crimestoppers anonymously on 0800 555 111.
