Sheriff's deputies have cleared an elementary school in Lakeside that was placed on lockdown for about an hour on Thursday.
Lindo Park Elementary School was placed on lockdown around 2:20 p.m. when deputies received a phone call from a concerned mother.
Though deputies are still investigating details, officials say a mother of a Lindo Park student may have called the school and said the child's father, who's her ex-husband, was coming to pick up the student, and was known to sometimes carry a firearm.
Deputies rushed to the school and placed the campus on lockdown as a precaution.
Officials say they temporarily detained a suspect, but that person has since been released. The person was not found to be carrying a weapon, officials confirmed, and there was never a parent on campus with a gun.
No one on campus was injured, officials said.
During the lockdown, officials went door-to-door, searching every room to ensure every student and teacher was safe.
By 3:40 p.m. the lockdown was lifted at Lindo Park Elementary School, and deputies remained on campus. The school is located at 12824 Lakeshore Dr.
