ANTIGO, Wis. (AP) -- Four people hurt when an SUV backed into a crowd at a Little League game in Antigo have been released from the hospital.

The victims include a 9-year-old boy who was pinned under the vehicle Monday night at Saratoga Park. The others include an 8-year-old boy, a 57-year-old man and 67-year-old woman.

Antigo Police Chief Eric Roller says a 73-year-old man was backing up when his foot slipped off the brake, hit the gas and quickly accelerated at the baseball diamond.

WSAW-TV says Antigo police and Langlade County sheriff's deputies are investigating.
