The woman tried to keep hold of her handbag, but the man pulled it from her and ran off in the direction of Maidencastle.
The mugger was a white man in his late twenties to early thirties, medium build, clean shaven and about 5ft 7ins.
He had short, black, swept-back hair and was wearing a black, short sleeved shirt, black jeans, dark-coloured shoes and had a black jumper tied around his waist.
