GREENSBORO, N.C.-- For nearly two and half hours on Friday, North Carolina A&T University students were put on lockdown by campus police.

Faculty were instructed to lock their doors and close their windows, as campus security and Greensboro Police searched the campus with K-9 units and a helicopter after receiving reports of a potential gunman on campus.

Students flocked to social media sites like Facebook, Instagram and Twitter letting friends and family know that they were okay.

After reviewing security video, the campus police determined that it was a man carrying an umbrella, not a gun who walked into the school's General Classroom Building.

Students said they're glad security took precautions anyway.

"I feel really safe and I'm really glad that the teachers were able to control us and control everything, and I'm glad everything is resolved now," student Nicholas Knable said.
