A woman posing as a customer held the door open for four masked men, two displaying handguns, who shattered display cases and stole valuables from a Smithtown jewelry store Wednesday, Suffolk police said.

Police said the owner and an employee of L.I. Gold Mine at 135 W. Main St. were held at gunpoint during the robbery, which happened at about 5:15 p.m. The five suspects drove off in a minivan, then parked it after driving a short distance, split up and fled in two other vehicles, police said.

No injuries were reported in the robbery, police said.

The property owner, Robert O'Connor, said in a new conference that the robbery took place shortly after he left the premises. "They obviously were waiting for me to leave in the truck," who said that's when "they sent her in, the woman, apparently looking for jewelry, and she left, and when she left is when she opened the door and held the door open. We have that on video."

"I'm still shaking," said William Billings, 61, of Smithtown, who observed the robbery — committed on a busy road at rush hour — from his vehicle about 20 feet away, deferring to the wishes of his female passenger who preferred that he get no closer.

"It was something right out of 'Blue Bloods,' let's put it like that ... it was just amazing," he said, referring to the popular TV crime show set in New York City. "I guess I was in the right place at the wrong time."

Billings said he saw the men jump out of a van.

"And I said to my passenger, 'They're going to rob the jewelry store, they're going to do a smash-and-grab'," said Billings, who pulled over and took a picture of the van, which he turned over to police.

Detectives are asking anyone with information about the robbery to contact 631-854-8452 or Crime Stoppers at 800-220-8477. All calls will remain anonymous.
