A French drugs squad officer has been arrested in the southern city of Perpignan on suspicion of stealing more than 50kg (110lb) of cocaine from Paris police headquarters, reports the BBC.
The unnamed officer, 34, was picked up while on holiday in the city on the Spanish border, officials say.
The theft of the drugs, which have a street value of some 3m euros (£2.4m; $4m), was a major embarrassment.
It appears they were taken from a secure room on 24 July.
CCTV images of a man carrying two bags into police headquarters that night, and leaving shortly after, helped investigators identify the suspect, police say.
