Man bailed over sex abuse at Swaylands School in Kent
A 70-year-old man arrested over historic sex offences at a school for children with behavioural difficulties in Kent has been released on bail.
The man was detained in Lancashire over assaults alleged to have taken place at Swaylands School, Penshurst.
He is the fourth person to be detained in the probe into the alleged offences, which took place between 1967 and 1993.
About 20 suspected victims living in the UK and abroad have been identified by police.
Kent Police said the three other men arrested were a 72-year-old from Norfolk, a 69-year-old from Edinburgh and a 60-year-old from Berkshire. All three are on police bail.
An additional three suspects identified during the latest investigation have died.
In 1993 two men were convicted of six sex offences against children at Swaylands.
