to speak about the abuse he endured at St Gilbert's
Police began investigating after the BBC reported what happened to boys at St Gilbert's in Worcestershire in the 1940s, 50s and 60s.
As more victims have come forward the inquiry has been extended into the 1970s.
Although many of the abusers are dead, the later time frame means some could still be alive and face prosecution.
The treatment of the boys, who were described at the time as "delinquent", came to light at the end of last year.
Aged between 11 and 15, boys were sent to St Gilbert's in Hartlebury after being convicted of petty offences such as vandalism and shoplifting.
Some were beaten and raped by brothers from the De La Salle order, which ran the institute under the direction of the Home Office.

Having heard reports of the recent investigation, Victor Aldridge, who was 12 when he was sent to St Gilbert's in 1963, told the BBC he was abused by Brother Roderick, who died in 2012.
Mr Aldridge, who has waived his right to anonymity, said: "It was continuous and went on throughout my time in the school."
"[Brother] Roderick was a horrible, vicious, violent man"
"He once asked me if I knew who broke his hair clippers, and when I said 'no' he bashed me all around the classroom and afterwards started stroking my neck and said he didn't mean it.
And then he interfered with me."
John - who does not want his surname to be used - was another victim of Brother Roderick.

"I just wish I could forget it all. I wish it would go. I wish it would go."
"If I could ask for anything out of this, it is for the other boys to come forward."
West Mercia Police has apologised after victims said they had tried to alert the force when they were still at St Gilbert's, and a review has been launched to discover why emails sent last year by a former pupil were ignored.
The Home Office has said "anyone who has been a victim of abuse, or knows of any abuse that has taken place at St Gilbert's Approved School, should report it to the police so it can be properly investigated".

April 2015 - An ex-member of staff at a Worcestershire school has been arrested on suspicion of indecent assault and grievous bodily harm.
The man was detained in Cambridgeshire, in connection with offences dating back to the 1960s and 70s, West Mercia Police said.
He has been bailed until June while investigations continue.
