Fish and Wildlife Conservation Commission officials are investigating a boating accident on the Alafia River that left four people injured Saturday night.
A 27-foot Baja inboard- outboard boat was heading east at 35 mph when it crashed into a piling of the Interstate 75 bridge about 9:30 p.m. Saturday, FWC spokesman Gary Morse said.
The crash totaled the boat and threw two passengers into the river, Morse said.
Authorities arrested the boat's driver, James Gregg McNeil, 48, of 5817 Fishhawk Ridge Drive, on charges of boating under the influence and violation of navigation rules.
He was released Sunday after posting $2,250 bail.
Rescue crews airlifted Marie McNeil, 49, of Lithia to Tampa General Hospital, where she was listed in fair condition Sunday.
McNeil and two passengers, Roy Nelson, 51, and Kimberly Saussy, 40, of Riverview, were treated for non-life-threatening injuries, Morse said.
