A radio DJ has spoken of her nightmare being stalked by a man for 13 years - who would call her 66 times an hour and even threatened to throw acid in her face . Gail Sayles became so terrified of her stalker that she began to self-harm and was afraid to go in to work at Sunrise Radio , in Bradford , alone . The 40-year-old says she finally has her life back after enduring more than a decade of sickening harassment because of stalker Mohammed Basharat Feroz . Gail Sayles ( pictured left and right , at work at Sunrise Radio ) endured 'sheer hell ' thanks to a stalker who harassed her for 13 years . Stalker Mohammed Basharat Feroz was detained indefinitely in hospital . Feroz , 55 , was detained in hospital indefinitely last month after Judge Jonathan Durham Hall QC ruled he posed a serious danger to the public and Sunrise Radio station in particular . Ms Sayles revealed seeing her stalker in court was only the second time she had seen him in person . But during years of what she described as 'sheer hell , ' Ms Sayles said authorities had refused to act because he had never physically attacked her - until last year , when he threatened her with acid attacks and vowed to put her in a wheelchair . She said : 'This man has been in my life longer than my own husband . It 's a huge weight off my shoulders as I can get on with my life . 'The calls would range from between 10 to 66 calls every hour . I once had 41 calls in 30 minutes . Ms Sayles says she became too afraid to go in to work at Sunrise Radio ( pictured ) in Bradford alone . She added : ' I was the only white person working at the station at the time so whether he fixated on that or the fact I was the only one answering I do n't know but it was 13 years of sheer hell . ' Ms Sayles , from Bradford , says the abuse started in 2001 after a rival business to Feroz 's was advertised on Sunrise Radio . After his business went bust , Feroz appeared to blame the station - and as Ms Sayles was the only person answering the phones at the radio station at the time , she believes this is why he became fixated on her . 'He became fixated with me , I think , because I was the only one on the phones so he constantly spoke to me when he called , ' she said . ' I had a police escort one night when I attended an election count for work . I did n't want to do my job anymore . It was so emotionally draining . ' Feroz was jailed in 2004 for a campaign of harassment against a number of people . Ms Sayles was a witness in this trial , but she said he blamed his jail sentence entirely on her . The jail time failed to deter his actions and after losing his mother early last year , the abuse became more sinister . 'He threatened to rape me and to kill me , ' she said . 'He would ring and ask if I could hear anything then I would hear what sounded like the loading of a gun . 'He even said I was a prostitute and that my boss was my pimp . It got so bad that my mum or dad had to take me to work . 'In March 2014 , he told me he was going to wait for me and throw acid in my face - that was the final straw . ' Feroz was found to be mentally unfit to plead a charge of stalking involving fear of violence in November last year - but a jury found he had committed the acts alleged . He appeared at Bradford Crown Court last month , where a judge ruled he be detained indefinitely in Lynfield Mount psychiatric hospital . Feroz appeared at Bradford Crown Court ( pictured ) last month , where a judge ruled he be detained indefinitely in Lynfield Mount psychiatric hospital . Ms Sayles added : ' I would urge anyone who is suffering with harassment of any sort to seek help . 'There are so many people who put up with this and feel helpless but they should n't . I stood up to my stalker and now I feel free . ' Ms Sayles said she was supported by The Suzy Lamplugh Trust , which helped her through 'the most difficult times ' . Judge Durham Hall told Bradford Crown Court that Feroz was not a bad man , but a 'poorly ' one . He said : 'The victim , the editor of Sunrise Radio , has been subjected to years of very intense unhappiness at the hands , or rather the words , of Mr Feroz . 'There has been a life-altering , intensely frightening , series of verbal attacks . ' Call the The Suzy Lamplugh Trust on 0207 091 0014 or visit www.suzylamplugh.org .
