“On January 6, the Ostankinsky District Court of Moscow ordered Robert Romanov Woodland to be placed in detention for a period of two months, until March 5, 2024,” the court said on social media.

He is accused of the “illegal acquisition, storage, transportation, manufacture, processing” of drugs and faces up to 20 years in prison.
