MOSCOW (Reuters) - The Russian Investigative Committee is continuing “active investigative activity” into the case of ex-economy minister Alexey Ulyukayev, the committee said on Friday.

Ulyukayev was dismissed and put under house arrest in November over allegations he extorted a $2 million bribe from top oil producer Rosneft. His lawyer says he denies the charges.
