Former Soviet spy Leonid Shebarshin, who was very briefly head of the KGB, was found dead Friday in his apartment in Moscow, an apparent suicide, officials said.

The 76-year-old left a suicide note, the state-run news agency Itar-Tass reported Friday, citing city police. A weapon was found near the body, Investigation Committee spokesman Vladimir Markin said.

The contents of the note were not disclosed "in the interest of the investigation," according to police, the news agency said. Shebarshin was alone in the apartment, it added.

According to Itar-Tass, Shebarshin was born in Moscow in 1935. He served as an intelligence officer under diplomatic cover in Pakistan, India and Iran and took high-ranking positions in the KGB beginning in 1983. He was appointed deputy chairman in 1989. He led the KGB for one day only, on August 22, 1991, and retired the following month.
