Rensselaer police said a vehicle was pulled over on East Street for a possible traffic violation and a 21-year-old passenger, whose name was not released, ran from the car, ran across tracks near an Amtrak station and jumped into the Hudson River, the Albany (N.Y.) Times-Union reported Thursday.
Police said the man, who was pulled from the water about 250 feet downstream, erroneously believed there was a warrant for his arrest.
"He just took a swim for no reason at all," Deputy Police Chief James Frankoski said.
The man, who was taken to Albany Medical Center Hospital for examination, may face charges of trespassing and resisting arrest, police said.
