National Express is offering a £1,000 reward to help identify a man who launched an attack on two bus ticket inspectors.
The passenger did not have a valid ticket for the journey in Birmingham on 24 January, and so was asked to leave the bus.
Upon leaving the vehicle, he attacked two ticket inspectors, leaving one unconcsious and the other injured.
Both men needed hospital treatment, and now National Express West Midlands released two pictures of a man who is wanted by police in connection with the incident, reports the Birmingham Mail.
The man was described as mixed race, and was wearing a blue Parka with a fur-trimmed hood.
Peter Coates Managing Director of National Express West Midlands said: "Any attack on our staff is completely unacceptable and we will do everything we can to catch those responsible.
"This unprovoked assault left two members of our hard working staff needing hospital treatment.
"We will do everything we can to find the individual responsible and press criminal charges, the first person to identify the man in these pictures will be given a £1,000 reward."
