The moment the Oheka Castle’s owner was shot in his Mercedes

Authorities on Thursday released surveillance video showing the man who shot the owner of Long Island’s landmark Oheka Castle as he sat in his Mercedes in the famed venue’s parking lot two years ago.

The clip, released by Suffolk County Police Commissioner Timothy Sini, shows Gary Melius walking to his luxe ride and climbing into the driver’s seat.

Seconds later, the shooter gets out of a Jeep Cherokee, slinks toward Melius’ car from behind and blasts him in the face at point-blank range.

He then scrambles back to his own vehicle, bobbling something in his hands — possibly the gun — before getting back into the Jeep.

Cops said at least three shots were fired before the shooter and the Jeep’s driver took off.

One bullet struck Melius, who survived, above his left eyebrow and traveled under his skin without penetrating the skull until it exited behind his ear.

Authorities have never cracked the case, and hope the video will spur new leads in their investigation.

The release comes roughly a year after Melius put up a $100,000 reward for the arrest of the bungling hitman.

Cops said Wednesday that the FBI had been asked to help with the investigation into the Feb. 24, 2014, attempted hit on the Long Island powerbroker.

The Queens-born Melius has been a longtime player in Long Island politics, contributing to both Democrats and Republicans, and had said he suspected a political rival could be behind the attack.

Oheka Castle, a 109,000-square-foot, French-style chateau, has been the site of numerous celebrity weddings and parties.

Ex-President Bill Clinton officiated at the wedding of disgraced ex-Rep. Anthony Weiner and top Hillary Clinton aide Huma Abedin at the Huntington hotspot in 2010.

John Gotti’s grandson John Agnello — a former star of “Growing Up Gotti” — got hitched there last October and raked in $2.5 million in gifts from assorted wise guys and other guests, Page Six reported at the time.

The Castle, built in the 1920s, is said to be the second-largest private home ever built in the US.
