OSHKOSH, Wis. (AP) — One man has died in the crash of a helicopter in the Fox River in eastern Wisconsin after it hit power lines.

The Oshkosh Northwestern says the Winnebago County Coroner’s office confirmed the death. The identity of the man was not released.

The helicopter plunged into the river on Saturday after hitting power lines and broke a propeller blade.

Authorities had to bring in special equipment to clean out downed power lines before they could search the water and bring the helicopter to the surface.

A photo of the helicopter showed its frame smashed and tail broker.

The Oshkosh Northwestern says divers returned to the water in the late afternoon Saturday and were able to recover the helicopter about 7 p.m.

It was not known how many people were onboard or what happened to them.

Witnesses said the helicopter crashed in Oshkosh after it hit power lines and broke a propeller.

Equipment had to be brought in to clear downed power lines out of the water so that divers could locate the submerged helicopter.
