A teenager has been arrested after a disabled man was taunted on a bus before being assaulted on the street.
The 66-year-old was travelling on the 300 bus when a group of youths began taunting him due to his disability.
They verbally abused him and threw cigarette packets at him.
The offenders followed the victim when he got off the bus at Daw Bank station and two were captured on CCTV punching him repeatedly.
He was taken to hospital for treatment to bruising to his head, face and body.
The incident happened at about 5.30pm on 9 November 2013.
Last night, Thursday 9 January 2014, a 15-year-old boy was arrested on suspicion of causing grievous bodily harm with intent.
He has been bailed until 23 January 2014 pending further enquiries.
As a result of calls from the public, police believe they have identified the three other youths they were trying to identify.
They are expected to be arrested in due course.
Detective Constable Drew McArdle, said: “We have had an overwhelming response from the public following our appeal for information.
“This incident clearly struck a chord with the general public and I would like to thank everyone that has provided information that has resulted in us identifying the people in the CCTV images.
“While feeling is likely to run high it is important all four are afforded the opportunity to provide their account of what happened.
“I am confident that the truth will out and justice for the victim will prevail but for that to happen it is important the judicial process is allowed to run its course.”
