A former teaching assistant has been charged with sex offences against pupils at an independent school in Shropshire.
John Addrison is accused of seven counts of indecent assault involving three children while working at Moor Park School in Ludlow between 1985 and 1988, Thames Valley Police said.
The 52-year-old, of Datchet Road, Slough, Berkshire, has already been charged with three counts of indecent assault on a child under 16 and one count of gross indecency with a child under 14, a police spokesman said.
Those offences were allegedly committed while he worked at Caldicott Preparatory School in Farnham Royal, Buckinghamshire, he said.
Addrison has been bailed to appear at High Wycombe Magistrates' Court on August 28.
The police investigation is continuing and anyone with information or concerns relevant to the inquiry should call Detective Sergeant Joe Banfield at the Child Abuse Investigation Unit on 101, or Crimestoppers anonymously on 0800 555111.
