Kaldip Singh, of Birmingham, said: "It is just a film with people acting. We are not saying people should take the law into their own hands but we are telling them to contact us if they suspect grooming is happening."

Mr Singh claimed "it would have cost an extra £5,000 to make it" if he had included a scene where the victim sought help from the police.

He said: "Of course if the victim is underage or has been raped then they should go to police but our experience shows that in the past the authorities have ignored the problem of Sikh girls being groomed by Muslim men in this country for more than 40 years."

Ofcom highlighted a scene 39 minutes into the film where the Sikh victim, called Japneet, is shown in the lounge of a Sikh Youth UK safe house after being sexually assaulted.

The scene shows a text being sent that “Some boys have hurt Japneet penji. We have to teach them a lesson."

One minute later into the film vigilantes are shown bundling one of the abusers into the boot of a car, while Sikh men armed with knives, bat and an axe are shown standing outside the home of another alleged abuser called Abdul.
