BOSTON (CBS) — Enes Kanter had a reason to celebrate Friday morning. The Celtics center tweeted that his father had been released from prison in his native Turkey, seven years after he was arrested.

“Wow! I could cry,” Kanter wrote on his Twitter account. “Today I found out that 7 years after arresting my dad, taking him through a Kangaroo court and accusing him of being a criminal just because he is my dad. MY DAD HAS BEEN RELEASED! This is due to the pressure we have put on the Turkish regime.”

Kanter has long been a critic of Turkish President Recep Tayyip Erdogan, and he has never been silent about his condemnation of the country’s leader. Kanter had two more tweets about his father’s release on Friday, pushing for more to question his regime.

Kanter’s clashes with the Turkish government date back years, and in 2017, it led to his Turkish passport being canceled. He has lived in fear of being deported back to Turkey, as Turkish prosecutors have sought an international arrest warrent for the 28-year-old.
