A man who identified himself as Alex Rodriguez’s nephew was kidnapped and held for ransom in a Midtown hotel Wednesday night when a deal over a $600,000 Lamborghini went south, according to police sources.

Norberto Susini, 29, told cops he is the retired slugger’s nephew and that he was held against his will by Lamin Vucetovic, 33, and Anthony Gilkes, 30, police sources said.

Susini sells exotic cars, sources said.

He met the pair in Times Square at 11:15 p.m. Wednesday to close a deal on the Lambo and they picked him up in a Rolls Royce, but Vucetovic tried to pump the brakes on the deal, sources said.

He demanded Susini return a deposit he put down on the car, and then Vucetovic and Gilkes allegedly held Susini against his will, according to sources.

The pair called Susini’s business partners and demanded a $35,000 ransom along with a car, but the partners called cops instead, NYPD officials said.

Cops arrested Vucetovic and Gilkes at 3:50 a.m. Thursday on kidnapping and unlawful imprisonment charges, police said.

Susini told police he’s A-Rod’s nephew, but a spokesman for the former Yankee said Susino is the son of Rodriguez’s half-brother Joe’s late girlfriend.

“This guy is 100-percent not Alex’s relative,” a spokesman for A-Rod said.

Vucetovic and Gilkes were awaiting arraignment Thursday.
