A fourth explosion rocked Austin, Texas Sunday evening; injuring two bicyclists as local and federal authorities scramble to find the culprit behind the seemingly random attacks before the attacker can strike again.
According to Fox News, the blast was possibly caused when the bicyclists triggered a ‘trip wire,’ signaling the suspect has a more “advanced” knowledge of bomb-making than previously thought and may be preparing to ratchet up the sophistication of their attacks.
“If this explosion was the result of a bomb using trip wire technology, that is showing a different level of skill above that we were already concerned that this suspect or suspects may possess,” said Austin Police Chief Brian Manley.
“That changes things, in that our safety message to this point has been involving the handling of packages and telling communities ‘do not handle packages, do not pick up packages, do not disturb packages,’” he added.
“Two men in their 20s suffered non-life threatening injuries in the blast, including one who had nails in his leg,” writes Fox.
If confirmed by the FBI and ATF, this would be the fourth explosion to rock the Texan capital in as many weeks.
