Police are investigating an incident of a man exposing himself in Northampton.
The offender had looked like he was waiting for a bus near the bridge over the A45 in Fishponds Road, Little Billing.
But as the victim approached, he walked towards the bridge and as she got closer she realised he had his jogging bottoms round his knees and was touching himself inappropriately.
The incident happened on Thursday, 9 March between 4.30pm and 4.45pm.
The offender is described as in his 20s, about 5ft 6in with a chubby build, short, dark, spiky hair and a tattoo on the front of his neck. He was wearing grey jogging bottoms, a red coat and T-shirt and was carrying a black rucksack.
