The eccentric Hall of Famer's trip was the second to the hardline Communist state this year to visit North Korean leader Kim Jong Un.

In March, Rodman was pictured with Kim, an ardent basketball fan, laughing and eating while watching an all-star basketball match.

He was criticized over the trip, which came amid escalating tension with North Korea threatening missile strikes on the U.S., South Korea and Japan.

Rodman has previously made no secret about his desire to help Bae . He once tweeted that he wanted the 30-year-old unchallenged leader of North Korea to "do him a solid" by freeing him.

Bae was sentenced to 15 years of hard labor in February after he was convicted of unspecified "hostile acts" against North Korea. The country's state-run Korean Central News Agency said he was arrested late last year after arriving as a tourist in Rason City, a northeastern port near the Chinese border.
