ORANGE COUNTY, CALIFORNIA — One person is dead and at least three more are injured following an explosion in Aliso Viejo Tuesday.
The deadly blast at the medical building was the result of an “intentional detonation,” according to NBC News, citing federal law enforcement sources.
When the news first broke, local media reported a car crashed into the building located at 5 Mareblu before the explosion was reported.
The scene was declared a second-alarm fire and a hazmat situation.
A nearby daycare was evacuated as a precaution.
NBC Los Angeles reported: Crews extinguished a fire that had erupted in the building that was under construction. Bomb squad investigators and FBI agents were looking into the cause of the blast, but authorities assured the public that there was no lingering threat to the community.
