Reports released by Wauwatosa police said two teens were planning to plant bombs at Wauwatosa East High School.
WTMJ-TV reported that police released the reports Friday. Police said the plan came to light after a classmate heard two teens talk about putting a small bomb in a stairwell that would lead people to another area -- where a bigger explosive would be waiting.
Police reports said the plan was dubbed "the kamikaze" by one of the teens, according to WTMJ-TV.
Police did not tell WTMJ if anyone had been arrested. Sgt. Brian Skornia told the Associated Press on Saturday that he didn't have all the details of the case in hand, and could not comment on whether there have been arrests.
Officers seized computers, cellphones, and materials the teens described as bomb ingredients.
The reports said the students had four different plans, including a possible suicide bomb.
Over the weekend, some area parents reacted to the news.
"I was very surprised," said Jeff Bartowitz. "I didn't think there'd be a bomb threat made at a school like this."
Despite the report, Bartowitz said he felt the school was safe.
"I feel that they're doing due diligence, and as long as it's being investigated, I feel very safe and comfortable having my daughter here," he said.
