Rochester police are searching for the armed men behind six robberies between early Friday morning and Saturday night, according to a Rochester Police Department news release.

The same suspects, armed with handguns, appear to be responsible for five of the incidents, while the sixth robbery attempt — involving a different man with a knife — is thought to be unconnected, police said.

On Friday afternoon, two black men in their late teens or early 20s invaded a home on 21st Avenue, armed with a handgun and wearing masks.

A spree of four similar crimes occurred Saturday beginning about noon. The first was at El Buen Liquor Store and involved three black men in their late teens or early 20s. They wore masks and had a gun.

Four hours later, police think the same three male suspects stole a red Toyota Yaris from a Godfather’s Pizza delivery driver at 60th Street and 25th Avenue NW. The car was recovered blocks away.

Two of the masked suspects appeared to strike again at a Motel 6 at 5:26 p.m.

Less than an hour later, four men armed with multiple handguns held up the Fairfield Inn and Suites. Police believe several of those men were involved in the earlier robberies. Surveillance images captured the incident. Wearing dark clothing, the men likely fled in a maroon Pontiac G6, police said.

Finally, in a separate incident about 6 p.m., a white man armed with a knife tried to rob a victim in Silver Lake Park.

No arrests have been made, the release said. Anyone with information should contact the Rochester Police dispatch line at 1-507-328-6800 or Crime Stoppers at 1-800-222-TIPS.
