Birdville Elementary School in Haltom City is no longer on lock down.
The campus was placed on lock down Tuesday morning due to police activity in the area.
According to police dispatchers, officers were called to the area after someone reported hearing a gunshot near the campus along the 3100-block of Bewley Street.
According to police, it now appears the gunshot was actually the sound of a car backfiring. The report of that sound led to the lock down, which was lifted at about 9 a.m.
All of the children at the school are OK.
Parents told NBC 5 that while they were pleased with the swift action by law enforcement, they were frustrated that the situation took place at all in light of the massacre at a Connecticut elementary school last week.
Some of those parents, including David Braziell, removed their children from class Tuesday over concern for their welfare.
“This is crazy after the things that happened over in Connecticut,” said Braziell. “Everybody’s going to be on scare [sic] right now, which is understandable.”
