A teenage girl was grabbed from behind by a man who tried to put a cloth over her mouth.

The incident occurred in St Albans yesterday, March 1, at around 4pm, shortly after the 17-year-old victim, a pupil at Townsend School, parted company from her boyfriend in Ladies Grove.

As she walked towards the playing fields off of Oysterfields she was approached from behind by a man who is reported to have grabbed her and put a cloth over her mouth containing some sort of liquid.

Her mother said: "Luckily my daughter fought back and punched him. She ran back to her boyfriend who then went after him and confronted him and threatened him off. They're both fine, the police cam immediately and searched the area.

"I'm so proud of my daughter for standing up to this scumbag as it could have been much worse."

The suspect is described as about 6ft tall and he was wearing a black shirt, blue loose-fitting joggers, a black and red jacket and dark shoes with white soles. He also had red headphones with a microphone. Any witnesses or anyone with information should call the non-emergency police number 101 quoting crime reference 41/16778/22.
