HOPKINTON (CBS) – A bullet was found inside Hopkinton High School Thursday morning.
Students were dismissed around 10 a.m. after the single round of ammunition was found in a common area, according to police.
Officers and the canine unit then swept though the complex.
“After a thorough search of the school no weapons or additional ammunition were found,” police said in a statement Thursday afternoon.
“We have no reason to believe that a weapon was actually on school grounds.”
The middle school, which is next door to the high school, was put in a shelter in place for more than two hours.
No other information is available at this point in the investigation.
