PORT JEFFERSON, N.Y. (CBSNewYork) — A man was rescued and was hospitalized with serious injuries late Thursday, after a car plunged into the water at the Port Jefferson Marina.

The car went into the water at the Brookhaven Boat Ramp at the Port Jefferson Marina around 5:30 p.m., according to Suffolk County police.

“The rain was coming down pretty heavy,” said Good Samaritan Neil Devine. “I don’t know how he ended up in the water.”

Good Samaritans jumped in to find the driver, who was stuck inside. The driver was in critical condition late Thursday.

“We were all throwing lines to him,” Devine said. “Someone brought out a rescue ring we attached to a rope that we found on the dock, threw it out, and the other man that had jumped in the water he was able to get him out.”

The man was being treated at an unspecified local hospital late Thursday, police said.

Members of the Suffolk County Marine Bureau Dive Team were dispatched to the water to check for possible additional victims, police said.

The investigation continued late Thursday. Officials believe the weather may have been in part to blame.
