Since Thursday, thousands of New Yorkers have taken to the street to voice their anger over police brutality and racism in the country.

More than 70 people were arrested after clashes with police in Manhattan's Union Square on Thursday. Some threw a trash can towards police and an officer was punched in the face.

On Friday, a generally peaceful demonstration turned violent in the evening in the Brooklyn borough. A police van was set on fire with some others destroyed.

In another place, protesters threw water bottles at police, according to videos circulating online, and over 200 people were arrested Friday.

On Saturday, more people joined demonstrations held at various locations across the city. Local media ABC News reported that around three dozen arrests had been made by the afternoon, mostly due to some protesters' attempts to take over highways.
