Man arrested over abuse at Swaylands School in Kent
A 70-year-old man has been arrested over historic sex offences at a school for children with behavioural difficulties in Kent.
The offences are alleged to have taken place at Swaylands School, Penshurst, between 1967 and 1993.
The man, from Lancashire, was arrested as part of an investigation into previously unreported child abuse at the school.
In 1993 two men were convicted of six offences at Swaylands.
Kent Police said three other men were arrested in 2012 during the latest investigation.
They are a 72-year-old from Norfolk on 18 July, a 69-year-old from Edinburgh on 11 July and a 60-year-old from Berkshire on 5 December. All three are on police bail.
An additional three suspects identified during the latest investigation have died.
Police said about 20 victims had been identified and were located in the UK and abroad.
Det Ch Insp Paul Fotheringham said: "This is a complex inquiry, where we have traced many people and records spanning a number of years."
Swaylands School was set up in 1942 and between the mid-1960s and 1994 was operated and managed by the London Borough of Barnet.
It taught pupils with learning, emotional and behavioural difficulties, aged between seven and 19 years old.
