An improvised explosive device was found in a mailbox in a Blaine County home Wednesday, according to the Blaine County Sheriff's Office.
In a news release Thursday, the sheriff's office says the device was neutralized with the help of the Twin Falls Bomb Squad. Authorities are seeking any information available on the incident.
According to the release, the device was found at about 4:30 p.m. by a caretaker for a residence on Hyndeman Drive, between Hailey and Ketchum. The bomb squad arrived on scene at about 8 p.m. Investigators determined that the device contained projectiles "capable of increasing the destructive force of an explosion." No one was injured in the incident.
Officials released few other details about the device, but noted it was not the type used in last week's Boston Marathon bombings. The sheriff's office told the Twin Falls Times-News that no information indicates there are more devices. The sheriff's office is not releasing pictures of the device because of the investigation, the Times-News reported.
"Without jeopardizing the investigation, we want the public to know that this was not a pressure style cooking device," Sheriff Gene Ramsey said in the news release. "This case is under investigation and will be a priority until the person or persons responsible are identified and apprehended."
The sheriff's office has turned to federal authorities for help with the case.
