Detectives are investigating a suspicious incident where a man wearing a black and red jacket attempted to grab a 16-year-old girl in Ladies Grove on Tuesday, March 1.
It happened around 4pm as the girl was walking along Ladies Grove towards the playing fields by Oysterfields.
St Albans Detective Inspector Ady Lysak said: “Thankfully, the girl managed to run away and was physically unharmed however this was understandably a frightening ordeal. This is a really unusual, isolated incident and a thorough investigation is well underway. No-one has been arrested yet but we are doing everything we can to trace the offender.
“Did you see anyone suspicious in the area around this time? Do you have a doorbell camera that may have captured the man? If you have any information at all, please get in touch.”
He added: “We will be doing reassurance patrols in the area this week and speaking to residents to find out exactly what happened at 4pm yesterday. We are also working with the nearby Townsend School.”
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 headphones that were red in colour with a microphone.
