A 28-year-old Grantham man has been arrested on suspicion of assault and bailed pending further enquries in relation to the attack last month on a 76-year-old bus driver.
At around 11.50am on Tuesday, June 3, a man got on to a bus as it pulled into a stop on the High Street and assaulted the male driver.
The long-serving employee of Centrebus was taken to Lincoln County Hospital to be treated for bruising and a cut to his face.
In a statement Commerical Director of Centrebus Dave Shelley said: “All at Centrebus were so saddened to hear that one of our long-serving colleagues was attacked whilst going about his daily work driving a bus in Grantham.
“Bus drivers quite reasonably expect to be able to work without fear of assault or intimidation - buses in the town are an essential public service carrying thousands of people very week.
“Such incidents on our buses are fortunately very rare and when they do occur are shocking and totally unacceptable.”
Police are still asking anyone with information to call 101 quoting incident 189 of June 3, or alternatively the independent charity Crimestoppers anonymously on 0800 555 111.
