BRIDGEWATER, Va. — A gunman shot and killed two campus officers at a private college Tuesday, prompting a protracted campus lockdown and search before the suspect was apprehended, state police and school officials said.

The lockdown began in the early afternoon when Bridgewater College officials sent out a tweet in the early afternoon warning students and faculty about a shooter on campus.

The college sent out a follow-up tweet about 2 p.m. saying police had apprehended a suspect after searching the campus but that students should continue sheltering in place.

No other injuries were reported.

At a news conference Tuesday night, Virginia State Police spokeswoman Corinne Geller said that the shooting happened shortly after the campus officers responded to reports of a suspicious man on campus around 1:20 p.m. She said that after a brief interaction, the man opened fire on the officers, shot them and fled on foot. The two officers succumbed to their wounds on the scene.
