Daood Hussain, of St Andrew’s Road, Birmingham, was found guilty of 12 counts of ‘assault’ and one count of blackmail at Birmingham Crown Court 15 Jan 2014 and was jailed for 17 years.

The court heard that 28-year-old Hussain had mocked up a leaflet which contained an image of his victim in her underwear and a caption with her contact details advertising her as a ‘call girl’.

Unemployed Hussain continued to threaten to share them with her family and friends and demanded ‘favours’ from her to stop him from doing so.

He continued to force the victim, aged in her 20s, to meet with him a number of times and then demanded that she hand over her £10,000 life savings or he would distribute the leaflet.

She did this but he did not relent and between 23 June and 19 July the pair met at different locations a further ten times − Hussain demanded ‘favours’ from her on each occasion.

Eventually in August 2012 she reported him to police for the blackmail and later disclosed to officers that he had been assaulting her.

Officers from the force’s Public Protection Unit launched an investigation and Hussain was arrested on 18 August 2012.

He pleaded not guilty to all charges but after an eight day trial at Birmingham Crown Court a jury convicted him of the crimes and he was sentenced to a total of 17 years behind bars.
