Same suspect linked with string of Aberdeen bus attacks
They all happened in 2018 and 2017.
Police think the same man could have been responsible for a string of assaults on buses in Aberdeen.
They have released a CCTV picture of the man they want to speak to.
He is 5ft 7in and speaks with a foreign accent.
But the attacks all happened in 2018 and 2017 - as well as the assaults on buses, one happened at a bus stop on Market Street.
Pc Brendan Clarke said: "I am keen to trace the man as he may have information that could assist with our investigation and I would urge anyone who recognises him to contact us.
"He is described as being around 5ft 7in, has a tanned complexion, brown hair and speaks with a foreign accent.
"Anyone with information is asked to contact Police Scotland."
