Four police officers have been served gross misconduct notices in an inquiry into failings to alert Cambridgeshire over paedophile Cambridge doctor Myles Bradbury.

Bradbury, who worked at Addenbrooke’s Hospital treating children suffering from cancer, was jailed for 22 years for sexual assaults on child patients.

The notices were served on the four officers who worked for the police’s national Child Exploitation and Online Protection Centre (CEOP) as part of an Independent Police Complaints Commission investigation.

CEOP was criticised because it had been given information about Bradbury by Canadian police in Toronto in July 2012, but the information was not passed on for 16 months, as the News reported.

He carried out his offences while working at Addenbrooke’s between 2009 and 2013.

There were 18 victims of sexual abuse and he was also found with 16,000 indecent images of children.
