Police are appealing for information following an assault on the Alcester Road near to the junction of Brighton Road in Balsall Heath that took place on Tuesday (15 October) between 3-4pm.
A man in his 70s got off a bus and was followed by another man who pushed him to the ground.
Detective Inspector Jim Church from FCID, said: “We are aware of a video that has been circulating online and we urge anyone who witnessed this nasty attack to come forward.
“He has suffered a number of cuts to his nose and both his elbows and this would no doubt have been a frightening experience for the gentleman who was just going about his daily business.
“I would urge anyone who has not yet spoken to us to get in touch if they have any information that could help our investigation.”
