A man fired a gun at a St. John's University student in a dormitory on the Queens college's campus, according to authorities.
The shot was fired inside Hollis Hall sometime before 2 p.m., according to police and a campus alert. No one was hit by the gunfire.
Police said that the gunfire stemmed from an altercation with four students inside a dorm room and that the suspects were trying to rob them.
The bullet went through a chair and struck a wall, police said. No one was injured.
The three suspects, -- ages 17, 18 and 21 -- ran from the dorm after the shooting and were captured a short time later. Police found a gun on one of the men.
Charges against the men are pending.
St. John's University said in the alert that there was no lingering threat to students.
Some students said they were surprised by the episode and that they didn't even know that anything was amiss on the campus.
