It's past curfew in the city of Buffalo, in upstate New York, but there is still a small group of protesters on the street.
They're gathered in Niagara Square, in the city's downtown -- where police officers pushed over and injured a 75-year-old man, Martin Gugino, during protests on Thursday night.
Video of the demonstration shows a row of officers walking toward Gugino and two pushing him. His head bleeds onto the sidewalk as officers walk past him, some looking down at him.
Gugino was hospitalized with a head injury.
New York Gov. Andrew Cuomo called the incident "wholly unjustified and utterly disgraceful," and said on Twitter that "police officers must enforce — NOT ABUSE — the law."
Officers plea not guilty: The two officers were suspended without pay, and pleaded not guilty earlier today to charges of assault in the second degree.
Following their suspension, 57 Buffalo police officers resigned from the force's emergency response team. They did not resign from the force.
