Police said a bomb threat made on Wednesday that led to the evacuation of three Hurst-Euless-Bedford Independent School District schools was not credible.

Central Junior High, Keys High School, and District Alternative Education Program classes were evacuated around 11 a.m., the district said. The Euless Police Department said a bomb threat was made against Keys High School and DAEP.

Just before noon, parents and guardians were told students could be picked up at the reunification center at the district administration building in Bedford. Officials said an ambulance was on site "out of an abundance of caution" and that no incident had occurred.

Euless police said K9 officers from DFW International Airport, bomb squad members from the Northeast Tarrant County Area Swat Team and bomb squad members from the Northeast Fire Department Association and North Richland Hills Fire Department assisted in clearing all three facilities, and no explosives were located.

"Euless criminal investigators learned the bomb threat was one of multiple sent to various central Texas schools," Euless police said in a statement. "The threats were generalized in nature and determined not to be credible. There is no ongoing threat to public safety at this time."

HEB ISD said classes resume as normal on Thursday.
