A German diplomat in Rio de Janeiro, Uwe Herbert Hahn, was arrested on Saturday night in connection with the death of his Belgian husband, police said.

Hahn said that his husband, Walter Biot, had died on Friday when he fell from their apartment in the Ipanema neighborhood after suffering a sudden illness.

But police arrested him on suspicion of murder after their forensics found bloodstains in the apartment and the autopsy of Biot’s body showed multiple wounds. Television images showed police taking Hahn away in a police car.

“The circumstances of the death are evident. We realized there was a violent death from the traces of injury in different parts of the body,” police investigator Camila Lourenco told reporters.

The foreign ministry in Berlin said its embassy in Brazilia and consulate in Rio de Janeiro were in close contact with the Brazilian authorities investigating the case. It declined to give any further details due to ongoing investigations and to protect individuals’ privacy.

Hahn will reportedly not enjoy diplomatic immunity due to the severity of his alleged crime.

Hahn had reportedly been married to Biot, a Belgian, for roughly 20 years. Police have not announced any potential motive for the alleged attack, and the German consulate in Brazil has yet to release a statement.

Police allege that Hahn also tried to clean up the crime scene before authorities arrived. He went on to tell them that Biot had been drinking and taking sleeping pills, according to ST.
