Four killed, three injured in shooting at Osmangazi University

A research assistant shot dead four staffers of a university and injured three others in central Turkey, according to security officials.

The incident took place at Osmangazi University in Eskişehir province, where Volkan B. -- the research assistant -- allegedly killed deputy dean Mikail Yalçın, faculty secretary Fatih Özmutlu, research assistant Yasir Armağan, and associate professor Serdar Çağlak, said the officials, who refused to be named due to restrictions on speaking to the media.

The suspect has been arrested while the motive behind the killings is yet to be ascertained, the sources added.

The university rector Hasan Gönen told Anadolu Agency that Volkan B. first went to the room of faculty dean, who was not there, and shot the faculty secretary.

"Later, he shot our vice dean, associate professor and a research assistant. Security guards followed him after he left the building with the gun, and police apprehended him after a brief chase," he said.

Gönen also said the suspect was being investigated internally over previous verbal attacks on university members.

"I guess he had some psychological issues," the rector said.

The governor Özdemir Çakacak also said the province's chief public prosecutor's office had appointed three prosecutors to the investigation of the incident.
