ROCHESTER, N.Y., JUNE 26 -- At least two armed men stole more than $10 million during an armored-car robbery this morning, authorities said.

Monroe County Sheriff Andrew P. Meloni said the robbery occurred about 7:20 a.m. in suburban Henrietta and "certainly was planned, no question about that."

The amount stolen was $10.8 million, according to other law-enforcement sources contacted by the Rochester Times-Union. Meloni said he could not confirm the amount.

The Federal Bureau of Investigation's public affairs office in Washington said records indicate that the largest amount stolen from an armored car in the United States was $11 million taken in 1982 from a Sentry Armored Car Courier Co. office in New York City.

About $1 million has been recovered.

In 1985, $7.9 million was stolen from a Wells Fargo depot in New York after four masked gunmen ambushed and disarmed four guards.

Sheriff's department spokesman Tom Ryan said the armored car robbed today was owned by Armored Motor Service of America Inc.

The car's male driver and a female employee had stopped at a delicatessen for coffee and sandwiches, Ryan said.

While the woman went inside, the driver was confronted by a gunman who entered the truck and took control of the vehicle, the employees told police.

When the woman returned, the gunman ordered the two to drive to a more rural location about a half-mile away, Ryan said.

The money then was transferred from the armored truck to another vehicle, believed to be a gray van, Ryan said.

The armored car company workers were taped-up and had their wrists bound, and at least one of the gunmen wore a mask, authorities said.

After the robbers fled in the second vehicle, the employees said they took about 15 minutes to free themselves, authorities said. They returned to the armored-car company offices and notified the sheriff's office of the robbery at 7:38 a.m., Ryan said.

The two employees were not injured, Ryan said.

"We're dealing with people who had a well laid-out plan," said Capt. Neil Flood, commander of the sheriff's office Criminal Investigation Division.

The money was to be transported to the Federal Reserve Bank in Buffalo, which serves as a source of coin and currency for banks throughout western New York. Banks, in turn, send surplus money to the Federal Reserve for storage.
