One man was seriously injured Saturday night in a boat crash on the Fox River, the Brown County Sheriff's Office said.
Around 8:33 p.m., a boat was reported to have crashed into shore near the Leo Frigo Memorial Bridge, according to deputies.
The crash happened on the north side of the Cat Island breakwall, 100 yards west of the shipping channel, the sheriff's office said.
The boat struck the rock breakwall and came to rest on the gravel road above it.
Three men and a woman were transported to a local hospital. One man had serious injuries, while the others were treated and released.
Speed and alcohol are believed to be factors in the crash and it is under investigation.
