LEE COUNTY, Fla.-The Code Red and lockdown was lifted at East Lee County High School just before 11 a.m. on Wednesday, according to authorities. 

The Lee County Sheriff's Office is investigating a threat in the area of East Lee County High School in Lehigh Acres. 

The Sheriff's Office said a call was placed to 911 at approximately 7:45 a.m. Wednesday reporting the threat. Sheriff’s Office Communications personnel were able to trace the call to a cell tower in the area of East Lee County High School, at 715 Thomas Sherwin Avenue, Lehigh Acres.

Due to the proximity of the cell phone tower to the school and the nature of the threat the school was placed on lockdown and deputies responded to the area to ensure the safety of the students, the staff, and the neighborhood.  The School Resource Officer and responding deputies searched the school and the neighborhood and located no threats. Aviation and K-9 units assisted in these searches.

The school instituted a Code Red early Wednesday morning, a spokesman with Lee County Public Schools said. The doors of the school were locked and the lights were turned off in all classrooms during the lockdown.

He stated that students were safe at all times and were kept in their current classrooms until the lockdown was lifted. 

Parents were not asked to come to the school, he said.

Anyone with information on this incident is asked to call Crime Stoppers at 1-800-780-TIPS (8477).  All callers will remain anonymous and will be eligible for a cash reward of up to $1,000.  Tips may also be made online at www.swflcrimestoppers.org or through the new TipSubmit/TipSoft app available on iPhones.
