MCALLEN – Authorities are investigating a small fire at the IDEA Tres Lagos Elementary School in McAllen.

It happened Friday morning at the location just off Ware Road, south of Monte Cristo Road.

Fire officials told CHANNEL 5 NEWS they believe the fire was intentionally started in a hallway on the second floor, but wasn’t large enough to trigger the sprinkler system.

All students and staff were taken to the IDEA Quest campus on Russell Road and 29th Street.

Fire investigators are currently on the scene.

IDEA Public Schools released the following statement:
