An elderly man is in hospital after he was assaulted in an apparent unprovoked attack on Easter Monday.
The incident happened on Bath Street at around 8.20pm by at least one young male who was with several other teenage boys and girls aged between 15 and 16.
Officers arrested a 15-year-old boy at the time on suspicion of grave and criminal assault but he has since been bailed.
The man in his 70s remains in the hospital after he sustained facial injuries.
Police want anyone who saw the assault or has any information to call them 01534 612612 or Crimestoppers anonymously on 0800 555111
