Officers have released CCTV images in order to trace a group of men after a woman and her daughter were attacked and racially abused on a bus in Uxbridge.
Detectives from Hillingdon have released images capturing a group of five young men they would like to speak to in connection with a racially aggravated assault on a west London bus.
The incident took place a Route U1 bus on the evening of Saturday, 8 August.
At the time, the bus was on Vine Street, Uxbridge heading in the direction of West Drayton, when a 40-year-old woman - who was travelling with her two daughters - was assaulted and racially abused.
All five men boarded the bus at Crown Walk, Uxbridge at approximately 19:45hrs.
Two of the group became involved in an argument with the woman over seating arrangements which culminated in both the woman and her 16-year-old daughter being punched and racially abused by two of the men.
They did not require medical treatment for their injuries.
The two men are described as white and aged between 16 and 20 years old. One was bare-chested at the time; the other spoke with a strong Irish accent.
The woman's 11-year-old daughter was also racially abused by the men, but was not physically injured.
