WAUWATOSA, Wis. (AP) -

Reports released by Wauwatosa police say two teens were planning to plant bombs at Wauwatosa East High School.

WTMJ-TV reports police released the reports Friday. Police say 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 did not tell WTMJ if anyone had been arrested. Sgt. Brian Skornia tells 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 say the students had four different plans, including a possible suicide bomb.
