STEUBENVILLE -- City schools were under a precautionary lockdown for about 90 minutes Tuesday morning.
It began about 8:15 a.m. when a Mingo Junction student being kept home from school due to illness saw a "threat on his Facebook page that was originally a Tweet.." the police report reads.
The report also stated that the Tweet came from "KnightSec" and that the students who have not been charged in the rape case were to come to a certain location today.
There has been unrest and turmoil in the town since two Steubenville High School students, both football players, were accused of the rape of a West Virginia girl, 16, in August.
Steubenville is a self-described "football-frenzied" town and the case has divided residents.
Police informed the school superintendent, who put all the schools on lockdown as a precaution at 8:30 a.m. Students were kept inside with the lights off and they were to stay away from the windows.
It was lifted 90 minutes later after police searched all the buildings. Police also added that, because of all the attention the district is receiving, there will be a guard stationed at each building until further notice.
Meanwhile, the situation remains tense in Steubenville after a weekend rally was held to protest alleged "special treatment" of two accused of rape.

Protestors dubbed it "Occupy Steubenville" and some wore Guy Fawkes masks.
Ma'lik Richmond and Trenton Mays, both 16 and members of the Steubenville High School football team, are charged with raping a 16-year-old fellow student at a party last August, according to statements from their own attorneys.
Mays is from Bloomingdale and Richmond is from Steubenville. Mays has also been charged with the illegal use of a minor in nudity-oriented material.
Their attorneys have denied the charges in court.
On Monday, attorneys for the two high school football players facing rape accusations here say they may try to have the case moved to protect possible witnesses.
Attorneys for the two 16-year-olds say potential witnesses have already been threatened and some are reluctant to come forward in court for fear of retaliation, including having their names and addresses published on the Internet.
Attorneys Brian Duncan and Walter Madison said Monday they're considering whether to make the request this week to move next month's trial, scheduled for now to start Feb. 13.
