Personal alarm scares off Glasgow sex attacker
A sex attacker fled after his victim activated a personal alarm on her phone.
Police are hunting the man who sexually assaulted the woman while she was walking along Ferry Road in the Partick area of Glasgow.
The 30-year-old was attacked at around 6.45pm on Friday, but the man fled when she set off the alarm on her mobile.
Police Scotland said the woman did not require medical treatment at the time but she has been left badly shaken and upset by the incident.
The suspect is white, 5ft 10in-5ft 11in, aged 20-25, with a slim build, and he spoke with a local accent.
He was wearing a black jacket, a dark beanie hat and dark jeans, and he ran off in the direction of the Clydeside Expressway.
Detective Constable Gordon Semple said: "I am appealing to people in the area to get in touch with us, the lady activated a personal alarm so I'm sure people will have heard the sound and perhaps went to the window to see what was happening.
"Perhaps you noticed something or saw the suspect run off. If you have any information at all, please contact us.
"It's imperative we trace this man and we are doing everything we can to locate him.
"Anyone with information is asked to pass it on, no matter how insignificant it seems, let us assess it and judge its relevance to our ongoing inquiries.''
Anyone with information is asked to contact CID officers at Drumchapel CID via 101. Alternatively, call Crimestoppers on 0800 555 111 where anonymity can be maintained.
