MOSCOW - A SENIOR economist for Russian state gas giant Gazprom has been found dead in Moscow, the company said Sunday, reportedly after shooting himself with a pistol presented by the Kazakh prime minister.

Gazprom said in a statement published on Russian news agencies that the senior economist for its financial-economic department, Sergei Klyuka, was found dead overnight Saturday to Sunday. 'The cause of his death is being investigated by the security services,' Gazprom said, adding that Klyuka was 'not a top manager at the company'.

The Interfax news agency quoted a source in the security services as saying that Klyuka's wife had raised the alarm after her husband left home on Saturday morning.

His body was then found overnight slumped behind the wheel of his Range Rover in an underground garage in the capital, with a pistol on the seat. 'The cause of the suspected suicide is being investigated. There was no suicide note,' the source told the agency.

The source said that the weapon was a Czech-made CZ-75 pistol that the economist had received as a gift by the Kazakh prime minister.

No further details were immediately available but the news website said Klyuka was 36 and had shot himself in the head.
