Moscow's Ostankino District Court said that on Jan. 6 Robert Romanov Woodland had been remanded in custody until March 5 on charges relating to the illegal acquisition or possession of drugs.

Russian internet news site Mash said that Woodland, 32, was charged with attempted large-scale production and sale of illegal drugs. He was detained on Jan. 5, Mash said.

A Facebook account in the name of Robert Woodland indicated that he had been working as an English teacher in Russia, and lived outside Moscow. It was not immediately possible to contact Woodland in Russian custody.

In 2020, Woodland, who was known to friends as "Rob", told a Russian newspaper that he was adopted in 1993 by U.S. citizens from an orphanage in Perm, in the Urals, and taken to live in the United States. He later returned to Russia.

He appears to have both Russian and American passports.

The U.S. says that several of its citizens are wrongfully imprisoned in Russia, including Marine Corps veteran Paul Whelan and Wall Street Journal reporter Evan Gershkovich.

The State Department has repeatedly warned all Americans to leave Russia immediately, citing the risk of wrongful detentions and harassment from Russian security services.

In Woodland's 2020 interview with the Komsomolskaya Pravda newspaper, he said that he had wonderful adopted parents in the United States.

But he wanted to search for his genetic mother in Russia and was eventually reunited with her on Russian state television.

"Mama was crying and begging for forgiveness. But I forgave her before this meeting. I've never been angry at her. I simply always missed her very much."

"I was drawn to Russia with a tremendous force. And here I am. I have decided to stay in my motherland forever," he said in the interview.
