A white security officer told police he was shot by a black man. 

Within minutes, 55 officers swarmed the campus, along with four police dogs and a State Patrol aircraft to search for the suspect.

Ahlers, the 'victim',  was taken to the hospital and released.  He is expected to make a full recovery.

At a news conference, police spokesman Mike Ernster said the campus had been on lockdown with “1,800 student held captive in their dorm rooms.” 

Neighborhood residents, shaken by reports of a gunman at large, asked police officers to check their houses.

Turns out, he’d shot himself.
