Cops in Norwich, England, say they're on the lookout for two Oompa Loompas and their associates after an assault last Thursday.

Police said a female suspect and three males, including two dressed as the Charlie and the Chocolate Factory characters, attacked a man in the street at around 3:30 a.m.

The man, 28, had just come out of a kebab house when the colourful gang jumped him, police said.

Two of the male suspects had "painted orange faces and dyed green hair and were wearing hooped tops," police said.

"One of the males in the group then pushed the victim to the floor before he got up. He was then hit on the head, fell to the floor and hit again," police said. "The victim sustained a cut below his right eye, two black eyes, a small cut to the nose and a cut lip."

Anyone with intel on the Oompa Loompas is asked to call police.
