A line of NYPD officers dressed in riot gear cleared out the last of the Occupy City Hall protesters from their month-long encampment in lower Manhattan early Wednesday.

The officers moved in at 3.40am, pushing around 70 remaining occupants – said to be a mixture of activists and homeless – north on Centre Street to Foley Square, where the crowd began to disperse.

Police said they gave the occupants a 10 minute warning before the Defund the Police activists 'left voluntarily'.

In total, seven people were taken into custody during the operation but charges are still pending.

One officer was injured after being struck by a brick, police said. Whether any protesters suffered injuries could not immediately be confirmed by the department.

After successfully moving the crowd on, the officers then began to take down the makeshift tents and remnants of the encampment, which first began on June 23 as a protest for police reform in response to the deaths of George Floyd, Ahmaud Arbery and Breonna Taylor.

Video footage captured the moment the officers, donning heavy gear, moved in on protesters who were heard chanting as they approached.

ABC 7 observed two people being taken into custody. One man also appeared to have suffered a medical condition and was taken away in an ambulance.
