A woman was indecently assaulted while walking through the centre of Aberdeen in the early hours of the morning.

The attack took place on George Street at around 12.45am on Saturday.

Police say the woman was not injured and praised her for seeking help quickly.

They believe a group of three unidentified men walking nearby may have witnessed the assault and have asked them to step forward.

Detective inspector David Howieson said: "This is a very concerning incident and we are working hard to trace the man responsible.

"While thankfully the victim was not injured, she has understandably been left shaken by this incident and I want to praise her quick actions in gaining help.

"A number of people helped the woman after the incident and we believe a group of three men walking in the John Street and George Street area may have witnessed the assault.

"They may have left the Mither Tap pub a short time earlier and I would urge them to come forward and speak to us.

"Additionally, we are aware that a young man walking on George Street wearing headphones waited with the victim and his father gave her a lift home in a white or light-coloured car.

"These witnesses also helped the woman look for her personal belongings that were dropped.

"I would urge these witnesses to come forward and speak to us as they may have information that is vital to our investigation."
