FORMER pupil Simon Wilshire was not sexually abused by Slade but described the former head teacher as "experienced in the art of beating".
Mr Wilshire, now 45, recalled the first time Slade hit him on his second day of school when he was 13 after being caught smoking.
He said: "We were called into his bedroom one at a time to be whacked on the bare backside.
"He always let us wait – he was a master at letting the fear kick in." Mr Wilshire added: "We would be beaten at least every week, pretty much at Slade's whim – it was relentless.
"The school was an incarceration facility where boys were beaten – and now it turns out they were molested there as well.
"Slade must never leave prison as long as he lives." Det Ch Insp Adrian Randall said: "While Slade may have committed these offences 30 years ago, for the victims their pain remains very real.
"I cannot begin to imagine how difficult it must have been for these men to come forward and try to make sense of what happened to them decades ago as defenceless young boys." He said more information had come to light as a result of publicity about Slade's trial and police inquiries were continuing.
