About 70 protesters picketed Thursday outside the B District headquarters of the Buffalo Police Department, a police department spokesman confirmed late Thursday.
Police made no arrests during the event, said Michael J. DeGeorge.
There were no major disturbances during the protest, he said. Police were on hand to monitor the situation, according to DeGeorge.
DeGeorge said it was not clear if the protest Thursday was headed by a specific group.
However, it came on the heels of a protest Wednesday night at the corner of Hoyt and Arnold streets, near the spot where 20-year-old Wardel Davis stopped breathing while struggling with police officers Tuesday night. No shots were fired during the scuffle, police said.
An autopsy Thursday failed to reveal a cause of death for Davis.
In addition to an investigation by the Buffalo Police Department, the New York State Attorney General's Office Thursday was looking into the circumstances surrounding Davis' death.
