Three Harrison teens have been charged in a beating and robbery of a man in White Plains Thursday while the search continues for two more attackers, White Plains police said Friday.

Kevin Doyle, 18; Salvatore Defonce, 18; and Domenick Ricotta, 19, all of Harrison, face felony first-degree robbery, felony second-degree robbery, and felony fourth-degree conspiracy charges in the attack on Westmoreland Avenue.

More charges may follow, Police Commissioner David Chong said.

Officers received a call at 7:48 a.m. Thursday from an off-duty FDNY firefighter who said he saw three men running across a park and jumping into a Mitsubishi convertible already occupied by two other men.

The firefighter also told police he saw what appeared to be an assault victim on Westmoreland Avenue and began to tail the car in his own vehicle, directing police to the corner of Walworth Avenue and Claremont Road, near the Bronx River Parkway entrance in Scarsdale, where they stopped the suspects' car.

Two men fled and three males in the car were arrested, police said.

K-9 units from the White Plains police and officers from the Scarsdale police joined the search for the two men who fled, police said.

The victim, a 34-year-old cabdriver from Port Chester, had been robbed of unspecified items, police said. He was taken to White Plains hospital and was released after being treated for a broken nose and swelling and bruising of both eyes, police said.

Ricotta's 1999 Mitsubishi Eclipse has been impounded as evidence, police added.

Doyle, Defonce and Ricotta were arraigned Friday in White Plains City Court before Judge Eric Press. A court spokesman said Friday that Defonce and Ricotta were released on $1,500 and $7,500 bail, respectively. Bail for Doyle was set at $30,000; his release status was unknown Friday. All are scheduled to appear again in court on Sept. 7.

Calls to Doyle's attorney, Angelo McDonald; Defonce's attorney, Arlene Popkin; and Ricotta's attorney, Felix DeVito, were not immediately returned Friday.

The fugitive pair are described as two teenagers: One 5-foot-9 to 5-foot-11, 180 pounds with unkempt hair and wearing a black hoodie sweatshirt on Thursday; the other 5-foot-8 to 5-foot-11, 190 pounds with short cropped hair, wearing pajama-style checkered pants and a white T-shirt on Thursday.

Police are asking anyone with information on the case to call the White Plains Police Detective Division at 914-422-6223. All calls will be kept confidential.
