Bloomington Police Chief Jeff Potts said police don't think there is any relationship between the man and the family of the child, who suffered "significant injuries" and was taken to a hospital.

Witnesses told police that the child may have been pushed or thrown from the mall's third level to the first floor, Potts said. He said the suspect immediately took off running but was quickly found and arrested at the mall.

A witness said a woman screamed that her child was thrown from the balcony.

Police don't have an idea about possible motive, Potts said.

"At this point we believe this is an isolated incident," Potts said. "We're actively trying to figure out why this occurred."

The 24-year-old is being held at the Bloomington Police Department.
