A Granite City elementary school was locked down Friday morning after a bus driver notified police about a man carrying a gun in a field behind the school.

The lockdown was lifted once police determined students were in no danger.

Major Jeff Connor with the Granite City Police Department said Worthen Elementary School was locked down at 8:30 a.m. Friday after a bus driver observed a person carrying what appeared to be a real gun across a field behind the school located at 3200 Maryville Road. The bus driver notified police.

Police investigated the incident and determined it was a parent carrying toy guns. Connor said a parent walked his two children to Worthen School, and once at school, he noticed the children had carried their toy guns with them to school. The guns were removed by the parent and he walked back home, across a field which is located behind the school.

Officers located the parent and observed the guns in his home and confirmed they are toys, Connor said, and the school's lockdown was lifted.
