All district schools in Steubenville, Ohio -- center of a highly charged teen rape case -- were under precautionary lockdown for about 90 minutes Tuesday because of a shooting threat made on social media, WTOV-TV reports.
The lockdown was lifted after police determined that the early morning threat was "non-viable," the TV station reported.
The sexual assault case involves two 16-year-old football players at Steubenville High School who face trial in February on charges of raping and kidnapping a 16-year-old West Virginia girl last August.
The case drew national attention -- particularly on social media sites -- after a video surfaced showing the defendants laughing about the alleged assault.
The video was reposted by the hacktivist group Anonymous, prompting allegations of preferential treatment for the members of the celebrated football team.
Steubenville City Schools Superintendent Mike McVey said that all the attention the district has received has prompted officials to station a guard at each school building until further notice, WTOV reported.
During the lockdown, the first ever by the district, the students were kept at the schools.
