AUSTIN, MAR 20 (DNA) – A package exploded early Tuesday at a FedEx distribution facility in Texas, news reports said, two days after the latest in a series of blasts in Austin attributed to a serial bomber.

This time the explosion rocked a facility in the town of Schertz, in the San Antonio area. Reports said one employee was injured.

*The Washington Post*, quoting the FBI, reported that the package had been bound for Austin, the state capital.

Hundreds of police officers and FBI agents are searching for a mysterious “serial bomber” after Sunday’s blast in Austin — the fourth this month — left two young men seriously injured and the city on edge.

Police said the explosion was connected to three previous bombings in Austin and the bomber used a tripwire in the latest attack, showing a higher level of skill.

“We’re clearly dealing with what we expect to be a serial bomber at this point,” Austin police chief Brian Manley told reporters.
