A month ago, Paris police busted a drug trafficking ring and recovered 112 pounds of cocaine, worth about $3.36 million. But now they have a new mystery to solve -- the stash has gone missing.

Officials said the drugs were placed in evidence bags and stored in a secure room at their headquarters, and were definitely there when the area was checked a little over a week ago. But on Thursday, the cocaine had disappeared, according to a report in the Guardian.

Despite the fact that the cops put their own detectives on the case, no leads have turned up.

“The investigation will look into whether the relevant rules were followed for the management of evidence in the offices of this brigade in particular, and at 36 Quai des Orfevres in general,” the Paris prefecture of police said in a statement, referencing the officers’ famous headquarters on the banks of the Seine.
