Federal investigators said a package that exploded at a FedEx facility near San Antonio in the early hours of Tuesday was believed to be linked to the string of bombings that has terrified Austin, the Texas capital, this month.
Special agent Michelle Lee of the FBI in San Antonio said she had no confirmed reports of any injuries in the blast. But the police department in Schertz, Texas, where the FedEx facility is located, issued a statement saying one person was treated at the scene and released.
A website that monitors fire and police activity in San Antonio said one person, a FedEx employee, suffered a non-life-threatening “percussion-type” injury.
Lee said it was still early in the investigation but “it would be silly for us not to admit that we suspect it’s related” to the four Austin bombings that have killed two people and injured four since 2 March. The latest bombing in Austin injured two men on Sunday.
Lee did not have details about the size, weight or description of the package that exploded in Schertz. The explosion happened sometime around 1am, she said.
Police and federal agents said earlier a Sunday night blast in Austin was triggered by a nearly invisible tripwire that suggested a “higher level of sophistication” than seen in three previous package bombs left on doorsteps.
The carnage was now random, law enforcement officials said, rather than targeted at anyone in particular.
Authorities did not immediately identify the latest victims but William Grote told the Associated Press his grandson was one of the two men wounded in south-west Austin’s quiet Travis Country neighborhood.
They suffered what police said were significant injuries and remained hospitalized in stable condition. Grote said the attack left what appeared to be nails embedded in his grandson’s knees.
