A kayaker was taken to the hospital Tuesday in critical condition after being hit by a ferry on the Hudson River.

It happened just before 6 p.m. Tuesday near Pier 79 at 39th Street. Police say emergency crews pulled ten people from the river after a New York Waterway water taxi collided with their kayaks.

They say five out of the ten were injured, including one employee of the Manhattan Kayak Company. Investigators say he suffered a severe arm injury.

"His bone was exposed," said NYPD Inspector David Driscoll. "He had lost a lot of blood and he was lapsing in and out of consciousness. He was rescued by Harbor Unit police officer Tommy Le who is an EMT. Tommy Le was able to apply a tourniquet."

"He was lying on top of the kayak and there was this pool of blood and we knew that we had to go over there and assisted him priority," the EMT said. No one else was seriously hurt and the investigation is ongoing.
