A 59-YEAR-OLD man arrested on suspicion of historic sexual abuse as part of the long-running St George’s School inquiry has been rebailed this afternoon.

The man, who is from the Ipswich area, spent four-and-a-half hours with detectives after returning to Martlesham police investigation centre at noon.

A spokeswoman for Suffolk Constabulary has said the suspect has been told by officers he will now have to return to Suffolk Constabulary headquarters at 10am on June 18.

The man - who taught at the former school in Great Finborough, near Stowmarket - was arrested in December.

The allegation against the suspect dates back around 30 years.

He is the fourth former teacher at the private school to have been arrested.

Earlier this year police revealed a fifth former teacher is being sought as part the investigation into historic physical and sexual abuse.

The inquiry, codenamed Operation Racecourse, has been under way for several years.

Derek Slade, head of St George’s School in the late 70s and early 80s, was jailed for 21 years at Ipswich Crown Court in 2010.

The 63-year-old was convicted of more than 50 offences, including a catalogue of sexual and physical abuse relating to 12 boys at the school.

Last year another teacher, Alan Brigden, was jailed for five years after being convicted of sex assaults at St George’s, when it was based in Norfolk. He had been extradited from Holland where he had been living.

The 67-year-old, who was known as Alan Morton when he taught at the school while it was based at Wicklewood, admitted 14 child sex offences when he appeared at Ipswich Crown Court.

At the time of Brigden’s offences in 1977 and 1980 he was teaching at a boys’ boarding school in Sussex, and then at the former St George’s School, in Norfolk.

Another former teacher Alan Williams was found dead at his Stowmarket home after being arrested on abuse allegations.
