Police have issued an image as part of their search for a man who hit and shouted at a crying baby on a bus.
The "shocking" incident took place on the number 29 bus in Luton on Tuesday afternoon (February 4) at around 2.50pm.
A 19-month old girl, who was sitting in a pushchair next to her mother, was hit in the back of the head, police say.
The infant, who had been crying when she was assaulted, was also shouted at.
The mother and baby had been travelling from Luton town centre to St Margaret's Avenue, also in the town.
Police say they will "not tolerate this kind of behavior" and have issued CCTV images of a man they would like to speak to in relation to the assault.
