Police are appealing for information to track down a thug who glassed and then headbutted a woman in a Doncaster town centre pub earlier this week.
The 25-year-old woman was left with serious injuries.
She is still receiving treatment in hospital following the attack in Urban bar on Monday evening.
The woman was drinking in the Cleveland Street bar at around 6.20pm on November 12 when she was attacked.
Officers have now issued a description of a man they want to trace in connection with the incident.
He had blond hair, was aged in his mid 30s, was slim and about 5ft 10ins tall.
Witnesses to the assault, or anyone with information, should contact South Yorkshire Police on 101 or Crimestoppers anonymously on 0800 555 111.
The attack is the latest incident at Urban, which was formerly The Saracen’s Head.
In August this year a woman was taken to hospital following a fracas with police outside the bar, in which an officer was injured, and last year a man suffered a broken hip in an assault inside the venue.
