Federal authorities and a county bomb squad disarmed an improvised explosive device hidden under a bridge in a rural Texas town on May 3.
It's not clear from reports who discovered the IED, but it was one of a number of suspicious-looking devices that prompted authorities to bring in a bomb squad from the McLennan County Sheriff’s Office to Rosebud, Texas, according to USA Today.
Police detonated the IED with a water cannon. No one was injured.
Authorities described the improvised device as "extremely dangerous" and said it was fortunate it was discovered and dealt with.

"Someone had made this to create lots of damage and harm," Sheriff Parnell McNamara said.
Authorities found shotgun shells and flammable liquid inside the IED, and told USA Today it was designed to explode and send shrapnel in a radius around the bomb.
The Bureau of Alcohol, Tobacco, Firearms and Explosives, a federal agency, took the lead on the investigation, according to reports. So far, authorities said they haven't identified any suspects or uncovered any reason why someone would build the device and place it in the rural Texas town of about 1,400 people about 150 miles northwest of Houston.
Investigators sent materials from the IED to a forensic laboratory for analysis, according to KARE.
