A drunken driver led deputies on a high-speed chase Saturday before barging through a parade route and injuring a total of four people, none seriously, authorities said.

The injured included two women and a 6-year-old boy. Parade bystanders were holding the 24-year-old driver on the ground when deputies arrived, said Sheboygan County Sheriff's Capt. David Adams.

Deputies received a call Saturday morning reporting an erratic driver on a highway, Adams said.

The man headed into Sheboygan, a city on Lake Michigan between Green Bay and Milwaukee, at speeds as high as 80 mph (129 kph).

His car hit a police captain in the leg before jumping a curb and careering into the route of a parade that was part of an annual bratwurst celebration. The captain was treated and released.

The suspect has not been charged.
