Norwalk police say no weapons were found after hundreds of backpacks were searched following a threat that put Norwalk High School into lockdown Friday.

Students and faculty left the building after being in lockdown without their backpacks and belongings so police could search for weapons. Students were released in waves.

Around 12 p.m. Friday, the Norwalk Police Communications Division received a very detailed, specific threat from an alleged student that they were inside Norwalk High School and were armed with a weapon inside their backpack.

Multiple units instantly responded, and the school was put under lockdown. Students were brought to the gymnasium and auditorium.

Naramack and Nathan Hale schools were also put in lockdown as a result.

After searching and establishing the scene was safe, police began investigating the threat and before 2 p.m. they began to release students in waves.

Many parents waited in parking lots across from the school to be reunited with their children.

"She just texted me saying, 'Mommy I love you,' and I was in Home Depot and I said 'I love you, too' and she said, 'I'm not scared, but I'm scared.'"

News 12 spoke with students who were wrapping up lunch in the cafeteria when they went in lockdown who felt nervous, since they didn't know what was going on.

This is the second threat made at Norwalk High School this week. On Wednesday, there was a bomb threat police say was deemed to be a hoax. They say there's no link right now but say two threats in two days is very suspicious.

Norwalk police say they will be escalating their presence at the schools next week, and the district will be bringing in counselors.
