A Turkish man who has been held in prison for over 3 years for alleged links to Gulen group, was released from prison for five hours early on Friday to see his 8-year old son, Ahmet, who has been suffering from osteoid cancer for more than a year.

Natali Avazyan, a Turkish human rights activist, said in a tweet on Friday that the father was released after she made a request from a “pro-government friend.”

The kid’s parents face prosecution in Turkey for having worked at a dormitory that had links to the Gülen group, accused by the Turkish government of masterminding a failed coup in July 2016. The group denies any involvement.

Ahmet went to Germany on January 26 for a cancer treatment without his parents as his father was in prison and his mother was subject to a travel ban.

He, however, returned to Turkey a month later as he reportedly failed to respond to chemotherapy
