A number Islamic books by Fethullah Gulen, a Bible and some other religious publications including the one on Jesus Christ have been confiscated as evidence as part of an investigation into the outlawed Kurdistan Workers’ Party (PKK).

According to Turkey’s state-run Anadolu news agency on Wednesday, a Mardin man identified as S.A. was arrested in an operation against PKK.

Police made a search at his home and seized copies of some books written by Islamic scholar Fethullah Gulen, a bible and many other books, most of them about Christianity.

As Turkish governments pinned the blame for the July 15 coup on Gülen and his movement, books penned by himself and those by sympathizers of the movement were banned by government decrees issued under emergency rules. The movement denies any involvement.

The government circles also criticize the movement for its interfaith activities, accusing the group of an alleged cooperation with the “the crusaders” to harm Islam.

Earlier, police in many other provinces displayed Gülen’s books as terror evidence.
