RIO DE JANEIRO (AP) -- Brazilian police say they are trying to find out why 2,600 cans of beer were delivered to a jail holding police officers charged with crimes.

The Rio de Janeiro radio station BandNews FM reports the beer was delivered Sunday to the prison in a northern suburb of the city.

Police inspector Waldyr Soares Filho tells the O Globo newspaper that officials are investigating the person who allowed the alcohol into the facility. He says he does not believe it was meant to be used for a party, but doesn't offer an alternative explanation.

Local newspapers last month published photos of a party at the same jail thrown by an officer charged with 16 murders. The man later escaped.
