Cybercriminals who hacked the FBI say they obtained highly sensitive medical information of thousands of special agents.

BBC News has seen samples of stolen 'fitness for work' medical tests, which contain information such as blood and urine test results and doctors' reports of illnesses such as 'shellfish and banana allergies'.

These records include the full names and addresses of the officers, as well as references to medical concerns such as "blood in the urine" and "high cholesterol".

Experts say the hack, which the FBI is investigating, could leave agents vulnerable to fraud, extortion and targeted attacks, and help criminals impersonate law enforcement officers.

Itay Maurer, vice president of information threats at Kato Networks, said: "This list exposes the medical records and medical information related to the employment of thousands of FBI agents."
