An Asian teenager was pelted with eggs and subjected to a barrage of insults at a Birmingham bus stop.
Police are treating the attack on the 18-year-old as a hate crime.
She was hit in the stomach by eggs thrown from a passing silver hatchback in Rectory Road, Sutton Coldfield, at 9pm last Friday.
A white man threw them and shouted racist insults.
He was in his late teens with short dark brown hair.
Det Sgt Simon Hanlon, of Sutton Coldfield police, said: “This was an ignorant and random attack on a member of the public and whoever is behind it should be thoroughly ashamed of themselves.
“We take all reports of hate crime extremely seriously and I would like to reassure local people that we will fully investigate what happened, including examining any nearby CCTV, in order to identify the offender.
“This matter – which is being treated as an assault – is currently thought to be a one-off and we are not aware of any other similar reports.
“However, if anyone knows of any racist attacks like this then please do not suffer in silence and let us know.
“Alternatively, if you suspect who may be responsible, don’t cover for their despicable behaviour – do the right thing and contact us.”
Anyone with information should call police on 101 or Crimestoppers, in confidence, on 0800 555 111.
