Two students are in the hospital and seven people have been charged following a stabbing incident that put Annapolis High School in Maryland’s capital on lockdown Wednesday morning.

The incident occurred at around 8:45 a.m. during a passing period, district officials and the Anne Arundel County Police Department said in a livestreamed press conference. One person had a knife, and two people went to the hospital with non-life-threatening injuries, officials said. School staff and resource officers quickly broke up the fight and confiscated the knife. The school then went into lockdown, which was lifted around 10 a.m., authorities said.
