The fourth explosion in less than three weeks in Austin, Texas, appears to be the work of a serial bomber, officials said Monday.
An explosion Sunday night had “similarities” with the three bombs that detonated in the Texas capital earlier this month, according to police. The devices, authorities warn, appear to be getting more sophisticated. The FBI has sent 350 special agents to Austin as well as extra bomb squads. Authorities have been calling on the person or people behind this month’s string of bombings to let them know the reasons for the attacks.
Meanwhile, they are asking residents of one neighborhood to stay indoors until 2 p.m. local time (12 p.m. PT) Monday.
