PEARLAND, Texas -

A Pearland day care center was evacuated for a brief time Wednesday afternoon after a bomb threat.

Police say a vague threat was called in from an unknown number to Children's Learning Adventure on Broadway. As a precaution, the center was evacuated.

We're told bomb-sniffing dogs from three agencies searched the building, but found nothing. The children were allowed back in the building after the all-clear was given.

Investigators are now trying to figure out who made the call and why.

Information regarding the identity of the caller or other facts of the case can be provided to Detective C. Turner at 281-997-4204.
