Police said they're preparing to charge a man who barricaded himself in his Fort Worth house with an explosive Saturday morning.
A witness went to a police substation at about 5 a.m. and told them a "possibly unstable" man in his 30s was at the home in the 5400 block of Whitman Avenue with what appeared to be bomb-making materials, according to police.
Tactical officers surrounded the residence and evacuated several neighboring homes as a precaution, according to authorities.
