CHASKA — An overhead heating unit fell in a kindergarten classroom at Guardian Angels Catholic School Thursday, striking three students.

One student was transported to the hospital via ambulance with a reported broken leg, said principal Nancy Ronhodve. The other two students remained at school and even participated in the relocated class Valentine's Day party.

The incident occurred around 2 p.m. Thursday. Chaska police and fire responded.

A note was sent home with students notifying parents of what had occurred.

The injured student was transported to St. Francis Regional Medical Center in Shakopee and later transferred to Hennepin County Medical Center in Minneapolis.

"I hope it was just because of traumatic effect," said Ronhodve.

Kindergarten classes are being moved to St. Francis Hall in Guardian Angels Catholic Church for the immediate future. Today’s preschool classes were cancelled.

Overhead radiators are only located on the lower level of the school where the kindergarten and preschool classes are held. According to Ronhodve, the lower level of the school will not be used until engineers have assessed the situation. For now, Ronhodve says the area has been secured.

Guardian Angels students were assembled Thursday afternoon and given an explanation of the incident before being led in a prayer for the students involved.

 "The three students involved in this highly unusual accident are in the thoughts and prayers of the remaining students and staff in the Guardian Angels community," said Ronhodve.
