Shopworker Hit On Head In Attack
A shopworker suffered a head injury when she was attacked in an unprovoked assault in a supermarket.
A man attacked the young woman at Asda Glenrothes without any provocation or warning at around 9.45am on Friday.
She needed medical treatment for the head injury and has been left badly shaken by the incident.
Police appealed for information about the attack in the Fife town.
Detective Inspector Steven Hamilton said: "Extensive enquiries have been undertaken and a man is now being sought for this incident.
"I must stress that we are not linking her place of work as relevant to the attack motive and we do not believe anyone else is at risk at this time.
"That said, it is vital we trace this man as soon as possible and I am seeking the assistance of anyone who may have seen the man.''
He added: "Anyone who was in the area of Asda Glenrothes from early evening on Thursday, October 2 until the late morning of Friday 3rd October is asked to call Police Scotland on 101 or anonymously to Crimestoppers on 0800 555 111.''
The suspect is described as 5'10" tall, of slim build, with dark hair, wearing black rimmed glasses and with facial stubble.
He was wearing a light coloured jumper, light coloured shorts with tight leggings underneath and black training shoes, and was carrying a rucksack and a blue and green tubular bag.
