64 year old Tahir Mahmood from Southall was sentenced for a number of offences including 10 counts of indecent assault on a male.
He also received a Sexual Harm Prevention Order.
Throughout the trial, Mahmood maintained his innocence when accused of the assaults against the three victim-survivors.
They were all children at the time of the offences.
Detective Sergeant Mitesh Mulji, who led the investigation, said: “Mahmood is a vile predator who has no place in society, he believed he had got away with his crimes, living in freedom for more than 30 years. This case demonstrates it doesn’t matter how much time has passed – we will do everything in our power to ensure predators are brought to justice.
“These three children are now adults and they have lived with this abuse for a very long time. I would like to take this opportunity to commend them for their tremendous strength and courage during this prolonged investigation and for giving evidence in court.
“I urge anyone who has been a victim of Mahmood to come forward to police. We will support you.”
During the two-week trial the court heard how Mahmood had sexually assaulted three young boys between 1984 and 2004.
In September 2018, a report was made to police, detailing how Mahmood had sexually assaulted a child, who was known to him, on multiple occasions between 1984 and 1991.
The victim-survivor who was aged between 10 and 17 years old at the time, was subjected to numerous sexual assaults after Mahmood became a friend of his family. He took the victim out alone in his vehicle to secluded areas in Southall and Hounslow, in order to abuse him.
Throughout the years, he groomed the victim by purchasing food and expensive gifts; he made threats to self-harm if the victim told anyone about the abuse.
Following an investigation by specialist detectives a further two victim-survivors were identified. The second victim-survivor was aged between 9 and 13 years old when he was sexually assaulted on multiple occasions. Mahmood would take him out alone in the Southall and Hounslow areas.
The third victim-survivor was 16 years old when he was subjected to a sexual assault in 2004.
Following the reports made to police, Mahmood was interviewed by police on two separate occasions and charged on 19 November 2021.
