Dubai police said on Sunday they sought a deputy prime minister of Chechnya, Adam Delimkhanov, in connection with the slaying of a former Chechen military commander, Sulim Yamadayev, shot down in a parking garage.

"The deputy prime minister of Chechnya is wanted by the justice system of the UAE and six people are suspected of involvement in the murder," Dubai police said in a statement.

Police said they held two suspects in connection with the killing -- one Russian and one Iranian -- and sought four more for questioning in connection with the case. They did not give names.

Yamadayev was shot on March 28 in the underground car park of a luxury seaside apartment block in Dubai, one of seven emirates that make up the United Arab Emirates. - Reuters
