The NSPCC has suspended its head of media relations after receiving an external complaint regarding the participation of a member of staff as a character witness in a court case.
Gerry Tissier has been sent home pending an independent inquiry. He denies that any complaint has been made against him personally.
Staff at the NSPCC have been instructed not to discuss the case until the end of the inquiry.
Director Mary Marsh said: "I have taken this complaint very seriously."
