A teenager has been jailed for more than a year after he viciously punched a 17-year-old girl in an unprovoked attack in Slough – leaving her with a fractured eye socket.

Mikolaj Szymczyk, 18, of Cotswold Close, Slough, started a verbal fight with the girl before punching her in the face, putting her in a headlock and continuing to punch her in an alleyway opposite Langley College, Station Road, at around 10.40am on April 30.

The following day, he was stopped and searched by officers and was found in possession of a weapon – a stick with screws in the end – and he was also in possession of a class B drug.

Szymczyk was arrested for GBH, possession of a weapon and class B drug, cannabis, on May 1 and charged on May 3.

He pleaded guilty to a count of grievous bodily harm without intent (section 20), possession of an offensive weapon, and possession of a class B drug, cannabis.

He was jailed for one year and four months, along with 146 days’ imprisonment to run consecutively, at Reading Crown Court on Monday.

Investigating officer Detective Constable Natasha Davis, of Slough CID, said: “This was an unprovoked nasty attack on a 17-year-old girl.

“She suffered a fractured eye socket as a result of Szymczyk actions.

“I would like to take this opportunity to commend the victim for her courage in coming forward and I hope this sentence helps her to get some closure on the incident.
