A controlling boyfriend installed CCTV in his home so that he could mock his girlfriend’s weight while he was at work, a court has heard.

Janusz Jelen, 34, has been convicted of inflicting psychological abuse on Agnieszka Mogilska after it emerged he installed a surveillance camera in his lounge to spy on her as she walked around their home.

Jelen, from Ashton-under-Lyne, Greater Manchester, would log into the device at work via his iPhone to scrutinise the mother-of-two’s appearance.

He would ask Ms Mogilska, a 37-year-old production worker at a lighting company, to raise her arm to see if she had any fat and suggest she wear trousers as he claimed her “thighs were shaking”.

The couple, who moved to the UK from their native Poland, had been dating for two years but their relationship began to deteriorate after Jelen laughed at her English pronunciation.

Jelen's belief that she was cheating led to him eavesdropping on her personal conversations with friends, Tameside magistrates court was told.

Police were eventually called in after the victim said she felt like she was living “in a mental hospital with 24 hours a day surveillance”.
