A predatory sex groomer who plied his vulnerable victims with neat vodka before abusing them has been jailed for almost eight years.

Quasim Inayat sexually assaulted a 15-year-old schoolgirl he persistently followed in his car and two women with mental health difficulties, molesting one and raping the other, Bradford Crown Court heard on Monday.

Inayat, 31, of Asthall Close in Keighley, was labelled “manipulative, determined and dangerous” by police, who again warned child sex abuse will not be tolerated.

The case of Inayat, who was jailed for seven years and nine months, came just days after two men were imprisoned for a total of 36 years for drugging and raping vulnerable schoolgirls they picked up off the streets of Keighley.

Uncle and nephew Shazad Rehman and Bilal Hussain raped a 14-year-old and each committed a brutal rape and assaults on other underage girls.

Rehman, 30, of no fixed address, was imprisoned for 18-and-a-half years, while Hussain, 23, of Neville Road Avenue in Leeds, received 17-and-a-half years at Bradford Crown Court on March 6.

This week, Chief Superintendent Angela Williams, Airedale and North Bradford divisional commander, said: “This is the second trial in a matter of weeks specifically relating to child sexual exploitation, and really represents our focus on bringing the perpetrators of these crimes to justice.”

Senior Investigating Officer, Detective Chief Inspector Chris Walker, said: “Inayat is a predatory sex offender who deliberately targeted young and vulnerable women for his own personal gratification.

“He displayed little or no regard for them as individuals, treating each with complete disdain.

“The evidence in the case clearly showed how he exploited his victims, using their absence of life experience to his own advantage.

“Using alcohol, he aimed to make them more compliant, in some cases leaving them incapable of resisting his advances.”

Inayat pleaded guilty to sexually assaulting a girl of 15 and a young mother with post-natal depression. He also admitted raping a woman with learning difficulties he met on a social networking site. All the offences took place between 2008 and 2012.

Inayat began following the teenager in his car when she was 14. He plied her with vodka and twice sexually assaulted her.

He lied to her about his age, pretending he was four years younger.

Inayat’s second victim was a complete stranger he drove to remote moorland above Keighley. He sexually assaulted her and she fled a mile through the darkness, dialling 999 on the way.

The third woman was raped when she was drunk and asleep after forming a relationship with Inayat on the internet.

His barrister, Katherine Blackwell QC, said Inayat was battling alcohol and cocaine, and that made him behave in an unacceptable way towards women.

Judge Jonathan Durham Hall QC told Inayat: “There is a theme in this case – your use of alcohol with these women in order to effect your desires.”
