MOSCOW, August 31 - RAPSI. The United States Attorneys Office is seeking a 30-year to life prison sentence for Russian pilot Konstantin Yaroshenko, according to court documents. Yaroshenko was indicted for conspiring to traffic cocaine into the United States.

Copies of court documents were made available to the Russian Legal Information Agency (RAPSI).

The Russian was arrested along with Nigerian Chigbo Peter Umeh in Liberia in May 2010. Soon after his arrest, Yaroshenko was extradited to the United States. However, the U.S. Attorneys Office of the Southern District of New York did not announce his arrest until June 2, 2010.

Chigbo Peter Umeh was sentenced to 30 years in prison on July 28. Meanwhile, the jury acquitted two other defendants in the case, Nathaniel French and Kudufia Mawuko, both Ghanaians.

A jury convicted Yaroshenko in April, although Yaroschenko denied all charges against him.

Yaroshenko is expected to be sentenced on September 7.
