Warwick Police are seeking assistance with a violent assault that occurred in a shopping centre car park on Marangaroo Drive, Girrawheen on Sunday 13 May 2018.
Just after 8am, a security guard was patrolling the outside area of the shopping centre when he noticed a pushbike in the middle of the entrance.
When the guard approached a man who was with the bike and asked him to move it out the way, the man became aggressive and verbally abused the guard.
The man then picked up a brick and threw it at the guard, hitting him on the arm causing immediate pain and then threatened him with a long piece of wood. The man got on his bike and then rode from the shopping centre.
Police have released a CCTV image of a man who they believe may be able to assist them with their investigation.
The man is described as brown skinned, around 18 years of age, slim build, wavy dark brown hair and approximately 165cm tall. He was wearing a black hooded jumper, long black pants and black shoes.
