A young girl was sexually assaulted as she walked along a Corby street on Sunday evening (September 14).
The 16-year-old was walking along Oldland Road at about 8pm when a man walked past her and made a sexual comment.
He then tried to start a conversation with the girl before grabbing her wrist and touching her inappropriately.
After the assault, he walked away towards Oakley Road.
The man told the girl he was from Slovakia. He had tanned skin and was between 20 and 30-years-old.
He was about 5ft 8in and was thin with short brown hair and a spiked fringe. He had a dark, stubbly beard and was wearing jeans and a hooded top which had a zip down the front and writing on the chest.
It is believed that before the incident, he had been in the shops in Butland Road.
