U.S. basketball star Brittney Griner was transferred last week from a detention center outside the Russian capital and is on her way to a penal colony, her legal team said on Wednesday.

The two-time Olympic gold medalist was arrested on Feb. 17, a week before Russia sent troops into Ukraine, at a Moscow airport with vape cartridges containing cannabis oil, which is banned in Russia. She was sentenced on Aug. 4 to nine years in a penal colony on charges of possessing and smuggling drugs.

Griner had pleaded guilty but said she had made an "honest mistake" and had not meant to break the law.
