NEW YORK -- Authorities in New York say five kayakers were injured when they were hit by a ferry departing a pier on the Hudson River.

According to CBS New York chopper reporter Joe Biermann, the dramatic rescues occurred around 40th Street near Pier 79.

Several kayakers collided with a ferry around 6 p.m. 

One person is in stable condition with a serious arm injury. The others had minor injuries. 

Police originally said 11 were hurt. 

People on other kayaks were being picked up by NYPD boats and the New York Waterways also helped out with the rescue operation.

Authorities are investigating whether the sun’s glare was a factor.
