Aaron Roach Bridgeman is back on TV tonight (December 12) with another hard-hitting documentary.

Weeks after his intense One Punch Killers premiered on Channel 5, the former face of SB.TV is back and this time he's profiling the people who take the law into their own hands in a bid to clean Britain's streets of criminals.

Aaron spends time with a group of vigilante paedophile hunters.

In Vigilante Britain: Street Justice, Aaron meets individuals and organisations that bypass the police in order to provide justice—hunting down those who do harm before the police can catch them.

Amongst those in the frame are 'paedophile hunters' group The Hunted One, who pose as children online to attractand confront—sex offenders.

The documentary explores whether these people are have-a-go-heroes or an irresponsible distraction for the police, with gripping consequences.

The documentary airs tonight at 9pm on channel 5Star.
