A woman suffered serious injuries to her head and face after being attacked by two other women in a nightclub, police said.
Tayside Police issued an appeal for witnesses almost a week on from the attack in Dundee's Liquid nightclub.
The 26-year-old victim was standing near the main bar on the ground floor at around 2.15am on Sunday December 23 when she was assaulted.
She suffered serious head and face injuries in the attack and subsequently received treatment at the city's Ninewells Hospital.
Officers said the assault is thought to have been witnessed by a number of people at the South Ward Road venue. They called for anyone who witnessed the incident, or who has any other information, to contact them urgently.
