Description A creep who sexually assaulted a 15-year-old girl and then walked along train tracks asked police "what's the problem?" Karol Jaworski, 40, approached the child, who was wearing her school uniform, in a shop and remarked "good arse". The victim then felt a hard slap on her bottom which caused a sting and when she turned around she saw Jaworski looking at her. A court heard, in a separate incident, the sex fiend walked along train tracks - after missing a lift - actions which led to severe delays on the line near Port Talbot, south Wales, and which cost National Rail £30,749. He initially told police: "I do this in Poland all the time – what's the problem?" Jaworski appeared in court on Monday, where he pleaded guilty to sexual assault and obstructing an engine or carriage of a railway. He was sentenced to a total of 16 months of imprisonment. He was also made subject to a restraining order for 12 months and to sex offender notification requirements for 10 years. Sentencing at Cardiff Crown Court, Judge Jeremy Jenkins said: "What is it coming to when a young schoolgirl cannot go into a shop without being sexually assaulted in the way in which she was by somebody like you?" In reference to the railway offence, the judge said: "You might be doing this regularly in Poland but you do not do it in Great Britain." Following the sex attack, Jaworski shouted: "F*** off, f*** off" as he left the shop in Bridgend, south Wales. Police were called but the sex fiend said it "came out of the blue" he could go to prison. In a victim personal statement read to the court by prosecutor Martha Smith-Higgins, the victim said: "I feel anxious about attending the town centre as it's where the incident took place. I feel different about attending the town centre and I have not been back since the incident took place. I feel like I can't attend school as I don't feel comfortable about older men. "I had a mark on my bottom which made me feel disgusted and sickened. It upset me about the force used. It left me feeling cautious of older men. I was wearing a school uniform and obviously I was a child." On February 21 this year, the British Transport Police received multiple reports of a man walking on the train tracks from Briton Ferry railway station towards Port Talbot Parkway. Jaworski was located trackside near the car park of Port Talbot Parkway, reports Wales Online. He initially told police: "I do this in Poland all the time – what's the problem?" and said he had been walking along the railroads after missing a lift. Ms Smith-Higgins said due to the defendant's actions trains had to be held and stopped for 56 minutes. Three trains were immediately affected and there were further delays throughout the evening. There were a total of 375 minutes of delays which cost National Rail £30,749. In mitigation, the court was told the sexual assault was "short-lived" and the defendant, who lives in Bridgend, was heavily intoxicated at the time through drugs. In reference to the railway offence it was said he left the tracks as soon as he was asked.
