North Yorkshire Police are appealing for information after a woman dressed as the Incredible Hulk is thought to have attacked a woman in York.
The attack happened just after 3am on Friday 26 April outside McDonalds on Blake Street.
A 17-year-old girl was left with bruising to her face and a black eye.
The woman suspected of the assault was covered in green body paint and had dyed red hair.
She is white, aged in her late teens or early twenties, around 5 feet 8 inches tall and of medium build.
PC Cheryl Hunter, of York police, said:
"This appears to have been a wholly unprovoked assault. Thankfully the injuries were not too severe. However, the outcome could have been far more serious.
"If you witnessed the assault or can identify the woman I need to speak to about this incident, I ask that you contact the police or Crimestoppers straight away."
Anyone who has any information that could help the police is being asked to contact York police on 101, press option 2 and ask for Cheryl Hunter, or to call Crimestoppers anonymously on 0800 555 111.
