His live-in girlfriend, who also was in the vehicle, was arrested for her alleged role in one of the thefts, police said.
The two are also under investigation for their possible involvement in recent similar thefts in Nassau County, Suffolk police said.
Daniel Cimolonski, 32, and Kristie Laird, 45, both of 182 Adams St., Deer Park, were arrested Wednesday at the intersection of Bay Shore Road and Crown Street at 4:45 p.m. by First Precinct Officer James Knoblach.
Cimolonski was charged with four counts of third-degree grand larceny, fourth-degree grand larceny, criminal possession of a controlled substance and resisting arrest. He also was charged with fourth-degree grand larceny stemming from a theft earlier Wednesday at a Burger King on East Main Street in Bay Shore, police said.
Police said Cimolonski also lived in South Setauket.
Cimolonski is suspected in thefts from the following stores, police said: Tourneau Walt Whitman, Walt Whitman Road, Huntington Station; Golden Island Jewelry, Veterans Memorial Highway, Commack; Zales Jewelers, The Arches Circle, Deer Park; and Diamond Exchange Jeweler, Route 112, Medford. It was not immediately clear what was stolen.
Suffolk police said that Nassau police are investigating potential links to thefts there.
Laird was charged with third-degree grand larceny and criminal possession of a controlled substance. Police said she was an accomplice in one of the jewelry store thefts.
Laird was charged in 1992 with falsely reporting an incident after police said she claimed to have been abducted at gunpoint by a stranger as she walked to her car at Hofstra University.
According to a story that appeared on Aug. 5, 1992, in Newsday, Laird, who was described as a married mother of two living at 182 Adams St. in Deer Park, had surrendered the day before to Nassau County police and was issued an appearance ticket.
The Nassau County district attorney's office said Thursday that Laird pleaded guilty to disorderly conduct in October 1992, and the falsely reporting an incident charge was dismissed. Laird paid a $250 fine, prosecutors said.
