Several students at a Lawrence middle school were injured Tuesday when parents helped them escape the building, through a broken first-floor window, as rumors of an intruder or an armed student spread.

According to the Lawrence Police Dept., officers saw the parents trying to evacuate the students, some of whom were injured by broken glass, as they pulled into Liberty Memorial Central Middle School late Tuesday morning.

The officers had been called to the school, 1400 Massachusetts St., after students alerted administrators of another student whom they believed had a gun, an LPD spokesperson Patrick Compton explained. School administrators locked down the school, as a precaution, and questioned the child.

Around the same time, parents were calling 911 about text messages they were receiving from the students about a possible intruder, Compton said. Some of the parents went to the school to get their kids.

Officials were able to determine the student did not have a weapon and none of the students, faculty, or staff were in danger.
