Turkish police on Thursday released seven people detained the previous day in connection with a mob attack on an Istanbul art gallery, DPA reported.
Turkish Tourism Minister Ertugrul Gunay told reporters that it appeared police could not confirm that any of the detainees had been involved in the incident.
The attack took place on Tuesday night, when more than 100 people had gathered for the opening at the Non and Outlet galleries in Istanbul's Beyoglu neighbourhood.
Some 30 men armed with sticks and stones attacked the galleries, smashing windows and spraying some of the guests with pepper spray. Five people were injured in the attack and taken to local hospitals, among them a German and a Pole.
The attackers were apparently angered by the fact that some of the gallery visitors were drinking alcohol outside, as well as by some of the art in the galleries, which they thought mocked religion and Mustafa Kemal Ataturk, the founder of modern Turkey.
Gunay and other members of the mildly Islamist ruling Justice and Development Party (AKP) on Thursday renewed their condemnation of the attack. At the same time, politicians and commentators called for more respect for Turkish customs and traditions in the area where the attack occurred.
