Police searched Rosemount High School Wednesday as a precautionary measure after they say bomb-making materials were found at a student's home, the Pioneer Press reports.
Lakeville police say the materials were found in a student's room on Flagstaff Court in Lakeville, which prompted the search.
"There were materials that could be used to make an incendiary device, but not an actual device," Lakeville Police Chief Jeff Long tells the Pioneer Press.
FOX 9 says two messages were sent to the parents regarding the incident. The first explained students were held in third-hour class for an extra 15 minutes while a search was conducted, but nothing was found. The second message said, among other things, the "school was never threatened, nor was there any evidence that the materials were connected to the school."
The search of the student's room happened after Rosemount High School officials contacted the student's parent over conduct concerns. The parent in turn reportedly searched the student's room, and called police after the bomb-making materials were found.
The student's residence and surrounding homes were evacuated while the Bloomington Bomb Squad removed the bomb-making materials, the Pioneer Press says.
The newspaper says police are still investigating, but the student likely won't face any charges.
In May, 17-year-old Waseca student John David LaDue was charged after authorities say he plotted to kill his family then go on rampage at Waseca High School, setting off bombs and gunning down students.
The teen was arrested after the Bloomington bomb squad executed searches at his home and storage facility in Waseca in connection with small explosive devices that were found on the playground of Hartley Elementary School in the city in March.
A Waseca County judge dismissed all four premeditated attempted murder charges against LaDue, saying the prosecution had not provided enough evidence to prove that LaDue’s actions went beyond “preparations.” Judge Gerald Wolf also dismissed two charges of first degree damage to property for the same reason.
Prosecutors have appealed those decisions.
Wolf let stand six charges claiming LaDue was in the possession of explosive devices, reportedly saying the prosecution had shown more than sufficient evidence to establish probable cause that LaDue did possess bombs.
