The officer sustained a cut nose and Green eventually was arrested after fighting with officers, authorities said.
In a separate incident on the same night, a Rochester police officer saw Williams-Smothers ignite a mortar-style, commercial-grade firework and throw it at a line of officers. The projectile made a loud noise, but no officers were injured.
Williams-Smothers fled on foot and was arrested a short time later. Inside his belt pouch were two similar fireworks, Kennedy said.
“These arrests are not about deterring free speech,” he said. “They’re about deterring violent and dangerous criminal activity.”
Officers have been targeted with rocks, bottles, lit fireworks and other projectiles amid the unrest, authorities said.
Rochester has had nightly protests over the death of Daniel Prude, a Black man who died a week after a March 23 encounter with police. Officers put a spit hood over a naked Prude — who had been suffering from a mental health episode — and allegedly pressed his head onto the pavement.
His death was ruled a homicide by “complications of asphyxia in the setting of physical restraint.” On Tuesday, Rochester Police Chief La’Ron Singletary and two other senior command staff members resigned. Two other officers voluntarily returned to their prior rank.
