Southbank International School's chair of governors is former Ofsted chief inspector Sir Chris Woodhead.
Responding to the FBI's warning that pupils at the school may have been targeted by US paedophile teacher William Vahey, he told The Guardian:
This is a completely shocking revelation.
We are co-operating with what is now an international police inquiry.
Vahey taught at the prestigious private school for four years and had a home in London, as well as in the US.
He was jailed for child sex offences in California in 1969.
