The teenage son of one of the men convicted of horrific child sex abuse in Rotherham has been found guilty of intimidating a female witness ahead of his father's two month trial.

Kaleem Ali, 18, of Masborough, left the woman 'shaking and crying' after subjecting her to terrifying threats after Qurban Ali was charged for his role in the brutal sex ring.

He denied doing anything wrong but was found guilty at trial yesterday.

Rotherham Magistrates Court was told that Ali approached the abuse victim - who gave evidence in the recent crown court trial in which his father was convicted - in the South Yorkshire Town in March last year.

Detective Constable Carly Booth said: 'Ali behaved in an intimidating and threatening manner towards one of the young women who courageously came forward to report years of sexual abuse.

'Ali's behaviour is inexcusable – he terrified this young woman, leaving her shaking and crying.

'Her strength has continued throughout this separate investigation and I hope she views today's result as another positive step forward.

'I hope the successful conviction offers further reassurance to victims that we take offences of this nature incredibly serious.

'Trying to scare or intimidate witnesses will absolutely not be tolerated and we will do whatever we can to bring these individuals before the courts.'

Qurban Ali, 53, was last month jailed for ten years after being found guilty of conspiracy to rape.

His nephews, brothers Arshid, 40, Basharat, 39, and Bannaras Hussain, 36, have all been sent down for lengthier terms after being found guilty of carrying out a catalogue of sickening sexual offences against young girls in Rotherham in the first case following revelations of mass grooming in the town.
