A Long Island professor accidentally shot himself in the leg while attempting to safeguard his gun before class Thursday morning, police said.
The licensed handgun went off in the hallway of a building at Long Island University on its CW Post campus.
Police said the round remained in the right leg of the 72-year-old professor, who has not been identified.
No other faculty or staff were present at the time, and the professor, who is also a retired New York City law enforcement officer, received help from students waiting to begin class.
He was transported by ambulance to an area hospital, and is expected to recover from his injury.
