A Harlem man was arrested after Suffolk County police said he tried to rob a man at knifepoint Tuesday in Bohemia while test driving a car for sale on Facebook Marketplace.

Police said Jalen Boynton, 20, met the man about 6:30 p.m. at his house on Cori Lane in Bohemia, where he planned to drive a 2020 Dodge Challenger T/A. The owner of the car drove with him for about a half mile before turning back home and turned off the car, police said.

Boynton grabbed the keys and started the car, but the owner turned it off. Police said Boynton threatened him with a knife and ran away with the keys about 7:15 p.m.

A Suffolk police canine unit and a helicopter helped in searching the marsh near Sunrise Highway and Pond Road, where Boynton was found just before 8 p.m., police said.

Boynton was charged with first-degree robbery and was set to be arraigned Wednesday morning at First District Court in Central Islip but no arraignment information was available online Wednesday evening and it was not immediately clear if he was represented by counsel.
