STATEN ISLAND, N.Y. - He didn't want her license and registration -- just her phone number, police allege.

A New Dorp construction worker posed as a police officer so he could pull over an 18-year-old woman and ask for her phone number, authorities allege.

Dennis Scamardella, 35, of the 2300 block of Richmond Road, was driving a black Cadillac with a blinking light installed in the dashboard, and at about 1 p.m. Nov. 24, he used it to stop the woman's car, police allege.

The woman, who was driving by the corner of Buel Avenue and Richmond Road in Dongan Hills, pulled over, and Scamardella pulled up directly in front of her and got out of the Cadillac, police allege.

He had what looked like a police shield dangling from his neck, and a pair of handcuffs hanging from his waistband, police allege.

"Hi, I'm Dennis. Do you know how beautiful you are?" Scamardella said, according to the criminal complaint against him.

When the woman asked if he was actually a real cop, he responded, "Yeah, don't you see my badge, cuffs and gun? Do you have a boyfriend? Give me your phone number," the complaint alleges.

Scamardella is not a police officer, but on Friday, he met the real thing -- when he was arrested by a detective with the NYPD's 122nd Precinct detective squad.

He's charged with two counts of second-degree criminal impersonation, both misdemeanors, according to information from District Attorney Daniel Donovan's office.

Scamardella was arraigned Saturday in Stapleton Criminal Court and released on his own recognizance until his next court date on March 19.

Attempts to contact Scamardella at his home and on the phone were unsuccessful Sunday.

He's the second man in a week to be arrested on charges of impersonating an officer. On Tuesday, police arrested Michael Paneque, 45, alleging he pretended to be an officer so he could stop, frisk and rob a woman in Rosebank on Sept. 6.
