Turkish media report a mob of 20 assailants carrying sticks and bottles attacked Radiohead fans who had gathered at a record store in Istanbul to listen to the band's new album.

The private Dogan news agency reported Saturday that one person was wounded in the incident Friday at the Velvet Indieground record shop.

The venue was locked Saturday morning. Posters advertising the streaming event of the album were ripped off nearby walls.

Rayka Simoni told Dogan news agency people were drinking beer and chatting when about 20 men began to throw glass bottles at them.

Video posted online allegedly showing the event suggested the attackers were angered by participants drinking alcohol during the holy Muslim month of Ramadan.

Radiohead issued a statement offering their "love and support" to Istanbul fans.
