A £5,000 reward has been offered in a bid to step up efforts to catch a man who sexually assaulted a young woman in Aberdeen.
The investigation was launched after the woman in her 20s was attacked in Union Terrace Gardens between 3am and 3.30am on January 28.
Crimestoppers has offered a reward of up to £5,000 for information that leads to a conviction in the case.
The charity said the reward would only be paid if information was passed to Crimestoppers directly.
Angela Parker, the Crimestoppers national manager for Scotland, said: “This attack was on a young woman in the heart of Aberdeen.
“We are now offering a substantial reward for anyone with information to contact Crimestoppers anonymously.
“By contacting Crimestoppers, via the phone (0800 555 111) or our anonymous online form, we don’t ask for any personal details, you won’t have to speak to the police, and you won’t have to go to court.
“Just tell us what you know, not who you are.”
In January, Chief Inspector Graham Mackie said “This was a serious assault on a woman in the city centre and we would urge anyone who may have been in the Union Terrace Gardens area at that time and who saw or heard anything untoward to come forward with any information they may have.
“I’d like to reassure the public that these types of incidents are unusual, however, we would encourage people to be vigilant.”
