The environmental crusader accused of dumping blue powder on the face of Wall Street’s famous Charging Bull was arrested Friday afternoon.

“Climate change is real and it shouldn’t be denied,” Courtney Frances Fallon, 33, told The Post, as officers put her in their SUV for a trip to court. “Please stop denying climate change. Draw the blue line!”

Fallon faces charges of vandalism and criminal mischief for the Thursday morning stunt, officials said.

Video captured near Bowling Green shows Fallon pouring a blue powdery substance over the bull’s head sometime before 7:30 a.m. Thursday, police sources said.

A blue sash was also draped around the nearby Fearless Girl statue that reads, “Draw the blue line.”

A Twitter account with the handle @drawtheblueline identified the substances poured on the bronze statue as chalk and corn oil. The 1st Precinct cops quickly cleaned up the mess.

“I don’t think it left a stain but it was definitely a poor choice,” Fallon said.
