Families whose children came into contact with convicted nursery abuser Vincent Chan have called for a full independent investigation after it emerged concerns were raised about him years before his arrest - but he was allowed to continue working with young children.
Chan, 45, a former worker at the Bright Horizons nursery on Finchley Road in West Hampstead, was jailed for 18 years in February after admitting 56 sexual offences against children in his care. Prosecutors described him as a "prolific sexual predator".
