Guernsey Police is investigating a leak to the BBC described by the force’s chief as “one of the most irresponsible I have ever come across”.­­­

The investigation was launched after journalists from the corporation were apparently tipped off about officers, investigating four deaths on the island of Alderney (pictured, Reuters), raiding a medical practice.

The BBC was thanked by the police for not acting on "the leak with the same recklessness that was displayed by the person who provided it to them".
