ANTIOCH, Ill. - A phone call threatening violence forced Antioch Community High School into lockdown Friday afternoon.
Law enforcement quickly determined the threatening call came from a cellphone inside the school. They then initiated a large-scale police respond around 1:52 p.m.
Just to be safe, Antioch police also responded to every school within its jurisdiction.
After a complete sweep of Antioch Community High School, police determined there was no bonafide threat and the lockdown was lifted.
"We would like to thank the parents and students for their patience and cooperation during this stressful situation," said Antioch Police Chief Geoffrey Guttschow. "It was the cooperation by everybody that helped the situation end quickly and safely."
The report of an active threat came one day after several school shooter hoaxes were reported in Wisconsin.
The investigation is ongoing.
