A 14-year-old girl was assaulted on her way home from school on Wednesday.
The teenager was under the M1 bridge on Leagrave High Street between 4.45pm and 5pm when a man grabbed her wrist, twisted her arm and pushed her against a wall.
He appeared to be searching her clothing to steal something but found nothing so continued to touch her over her clothing.
The victim called for help and a member of the public assisted her and she managed to break free from the offender and ran from the scene.
Det Con Phil Raikes said: “This is an unusual crime and we want to ensure we stop this person from assaulting someone else. I would urge the member of the public who assisted the victim to contact officers as he may have vital information that could help identify the offender. I would also encourage anyone who saw the incident or anyone who can help identify the offender from the description given to also come forward and speak with officers.”
The offender is described as a black man with a dark complexion, 5’7” to 5’8” tall with a large muscular build, black beard and spoke with a deep voice and a strong Caribbean accent.
He wore saggy dark blue jeans, a black Adidas hooded top with white stripes down the sleeves and a white zip.
