AKIPRESS.COM - Officers shot and killed a suspected gunman after a shooting at Florida State University early Thursday that wounded three others and prompted an alert for students to take shelter, police said.

The shooting happened at a library on campus and officers opened fire after the suspect shot at them, Tallahassee Police spokesman Dave Northway said. It was not immediately known if the wounded were shot by the suspected gunman, reports Associated Press.

Northway said authorities did not believe there were any other threats related to the incident. The lockdown was later lifted and the school said on its verified Twitter account that the area was secure.

Strozier Library, a multistory building at the center of the Tallahassee campus, was roped off with police tape. John Ehab, a sophomore from Tampa, said he was on the library's third floor when he heard multiple gunshots.

"Everyone heard them," he said. People took cover in the book aisles to hide from the gunman in case he came onto the floor, Ehab said. Freshman Nikolai Hernandez said he was in his dorm room across from the library when he heard five or six rapid gunshots.

"It was a consecutive bop, bop, bop, bop, bop," Hernandez said. "It makes me definitely a little bit nervous. I was supposed to be in the library. I had a paper to do and I got a little bit lazy and decided not to do it."

He said he has friends still locked inside the library two hours after the shooting. A campus telephone alert urged people to take shelter in a nearby building and stay away from doors and windows. Campus and Tallahassee police declined comment.

Florida State President John Thrasher, who took office earlier this month, said by phone that he is in New York City and had no first-hand information. He said he was making arrangements to hurry back to Tallahassee.
