A Melville man was arrested late Monday night in connection with a hit-and-run collision that killed an Amityville bicyclist in Dix Hills earlier in the day, Suffolk police said.

Alberto Dibernardo, 28, of Randi Court, was charged with felony leaving the scene of an incident without reporting involving a fatality after his black, 2010 Jeep Wrangler struck and killed Ricardo Fernandez, 44, just off of the Long Island Expressway, police said.

Fernandez was pronounced dead at the scene after a passing motorist called 911 just after 10 a.m. Monday to report seeing a body on the side of Express Drive North about a quarter-mile east of Burrs Lane. Police said they didn't know when the crash occurred.

Dibernardo was arrested at 7:15 p.m. at the Second Precinct in Huntington after a police investigation, said Det. Sgt. James Madden, of the Suffolk County Police Vehicle Crime Unit. He was held overnight at the Second Precinct and is scheduled to be arraigned in Central Islip Tuesday.

Fernandez was wearing a green, white and yellow cycling shirt and cycling shoes. He was riding a blue and orange LeMond racing bike.

Anyone with information should call the Vehicular Crime Unit at 631-852-6555 or Crime Stoppers at 800-220-8477.
