A woman who was out jogging was attacked from behind by a man on a bike.
The incident happened on Claverhouse Road in Dundee at around 7.50pm on Monday.
The victim was running near to the Old Glamis Road roundabout when she was briefly assaulted as the man cycled past.
Police said she was “not badly injured, but was left shaken and upset”.
The man – who was in his late teens or early 20s – had medium-length light-brown hair and was wearing rectangular glasses.
He was also wearing a dark-coloured hooded top and light-grey jogging bottoms.
His bike was grey.
A Police Scotland spokesperson said: “This area is popular at the moment with people taking daily exercise, and it is hoped that someone in the area may have seen this cyclist around the time of the incident.”
