TOTOWA, N.J. (AP) — The manager of a popular northern New Jersey diner who felt he was not getting his fair share of the profits tried to have his uncle, an owner of the restaurant, killed by a hit man, the authorities said on Wednesday.

The nephew, Georgios Spyropoulos, 45 and manager of the Tick Tock Diner on Route 3 in Clifton, asked an undercover trooper posing as a hit man to kill Alexandros Sgourdos, 57, and to dispose of the body, the authorities said.

Mr. Sgourdos also manages the Tick Tock Diner in Manhattan, a popular tourist spot at 34th Street and Eighth Avenue, near Pennsylvania Station.

Officials said Mr. Spyropoulos resented the control his uncle exerted over the New Jersey restaurant, which was featured on Guy Fieri’s Food Network show “Diners, Drive-Ins and Dives.” They said he also felt his uncle was taking an unfair share of the profits from the classic chrome diner, a popular spot among fans attending Jets and Giants games at the stadium in the Meadowlands a few miles away.
