Police say they responded to the call for a stranded dolphin and determined it got stuck due to the low tide.
They say several officers and another person entered the mud to help the dolphin.
They managed to free the dolphin by lifting it onto a kayak and dragging it approximately 300 feet through knee deep mud to an open area of water.
The rescuers then placed the dolphin in the water and made their way back to shore.
Unfortunately, despite their heroic efforts, officials announced Wednesday that the dolphin had passed away.
This dolphin wasn't the first to make headlines in the area over the last week.
Last Wednesday, a pod of dolphins was spotted swimming in the East River, to the delight of New Yorkers who saw the rare sight.
