Peaceful demonstrations are welcome, but violence is not acceptable - that's the message from the Mayor Bill de Blasio after dozens of people were arrested in a series of protests that took place in Manhattan Wednesday.

The mayor says that violence will not be tolerated.

The three rallies started peaceful, but authorities say during those rallies 25 people were arrested for attempting to hijack a peaceful protest by lighting fires, throwing garbage and eggs. They also found knives, stun guns and m80 fireworks.

Some of those people arrested have been charged with obstructing governmental administration, harassment and criminal possession of a weapon.

The NYPD says Elizabeth Barter, 28, was arrested and charged with resisting arrest, obstructing governmental administration, unlawful possession of noxious matter, disorderly conduct, and harassment. 

The NYPD says 23-year-old Christine J. Brown was also arrested and charged with assault, resisting arrest and obstructing governmental administration.

They also say 25-year-old Terrence M. Lewis was arrested and charged with resisting arrest, obstructing governmental administration, criminal possession of a weapon, disorderly conduct, and unlawful possession of marijuana. 

The protests were organized by activists who are demanding for every vote to count as we continue to wait for election results. There were dozens of videos on social media showing clashes between officers and protesters.

News 12 is told 32 other people were given summonses.

The NYPD also briefed the public Thursday on election security. 

The NYPD says an officer was pushed to the ground and had a chain pressed against his throat near Bond Street and Broadway in Manhattan Thursday night.
