CHEEKTOWAGA, N.Y. — It’s a ‘‘miracle’’ more people weren’t hurt when a man dressed in camouflage, wearing body armor, and armed with two rifles sprayed a retail store with bullets, wounding one man, before being tackled by police, authorities said Wednesday.

Police in Cheektowaga, near Buffalo, said the gunfire erupted around 2:45 p.m. Tuesday outside a Dollar General store. The gunman fired repeatedly at the store’s entrance from outside while several customers and employees were inside, police Chief David Zack said.

When police arrived, witnesses pointed out the gunman, who attempted to run away after being hit by a bystander’s vehicle before being tackled by officers.

A 53-year-old Cheektowaga man suffered a gunshot wound to his shoulder, officials said.

Police identified the suspect as Travis Green, 29, of Buffalo. His mother said her son and his wife had recently broken up.

‘‘It is a miracle I’m not reading the names of the deceased,’’ Zack said. Considering the number of rounds that hit the store, those inside ‘‘clearly were extremely lucky,’’ he said.

A pump-action, AR-15-style rifle was used to fire at least 20 rounds during the shooting, police said Wednesday.

Green was arraigned on charges that included attempted murder, assault, criminal use of a firearm, and resisting arrest.
