STATEN ISLAND, N.Y. -- A man was rescued by an off-duty Port Authority Police Department officer while attempting to swim from Bayonne, N.J. to Staten Island Sunday afternoon, a Port Authority spokesman said.

It was previously believed the man swam from Staten Island and was heading toward New Jersey.

A Port Authority investigation revealed that the man swam from Staten Island to the location where an off-duty Port Authority Police Department ESU officer found him, the spokesman said.

After being discovered, the man was brought to shore and was taken to a medical center by EMS, authorities said.

A Port Authority spokesman did not immediately have information regarding the man’s condition.

The Advance previously reported that emergency radio transmissions indicated that authorities were initially responding to unconfirmed reports that a person jumped from the Bayonne Bridge just after 12 p.m.
