The campus of Virginia State University lifted a roughly two-hour lockdown early Friday after a male was shot and critically wounded, in the second shooting at the school in less than a week, police said.

Responding officers found a male suffering from gunshot wounds in the 1 block of Hayden Street after a report of the shooting at 11:06 p.m. Thursday. The victim, who was not identified, was taken to a hospital with life-threatening injuries, Chesterfield County police said in a statement.

"At this time, police believe this is an isolated incident, and there is no further threat to the campus," the statement said.

VSU police were on the scene and told students the campus was on lockdown in a tweet at 11:37 p.m. Thursday: "Go/Stay indoors. Avoid area."

The campus alert system notified students to shelter in place, Pamela Turner, the school's director of communications, said in a phone interview early Friday.

By 2:20 a.m., police at VSU said in a Twitter message that officers had "cleared the scene" and the lockdown was lifted.

In a separate incident last Saturday night, police locked down the campus following a shooting during homecoming weekend, when a man suffered non-life-threatening injuries. Officials called it an "isolated" incident. There was no immediate information to determine whether the two incidents were connected.

The wounded man on Saturday was not a student, school officials said.

There were no further details about the incident early Friday.
