While violent crime is typically committed by men, every once in a while a young girl shocks the world.

It took nearly killing a hardworking, octagenarian Manhattan building concierge with a machete to get this ticking timebomb off the streets.

Deashe Calhoun, 20 — free despite seven prior busts, several of which involved the deadly weapon or other knives — was ordered held on $500,000 bail Thursday after being charged with slashing the 82-year-old Upper West Side doorman in an unprovoked attack.

She was arraigned in Manhattan Criminal Court for the bloody assault that left Hubert Meulens with a bloody skull fracture.

“Thank God,” Meulens’ son, Peter Marcel, told The Post. 

“That’s appropriate. It doesn’t make sense that she was on the streets in the first place. This decision sends the correct message.”

Manhattan prosecutors had requested the high bail during the hearing. Calhoun’s lawyer asked for time to “research” his client’s case.

Bail was also set at $1 for a separate menacing case against Calhoun from Aug. 25.

Calhoun was hit with attempted murder, assault, and weapons possession in the alleged attack on Meulens, who remains hospitalized.

Cops said Meulens tried to stumble away after the brutal attack but Calhoun doused him with bear spray. According to a criminal complaint filed Thursday, Meulens was trying to find a cop when he was sprayed, “causing burning to his eyes and difficulty breathing.”

“I am not angry,” Meulens told The Post from his hospital bed Wednesday. “I would suggest she needs to be examined by a doctor. She needs psychiatric help.”

Police said Thursday there was no record of prior emotional disturbance reports involving Calhoun, but she piled up more than a half-dozen prior arrests.

According to sources, Calhoun had been busted twice in August — for carrying two knives on a Brooklyn train and for wielding a machete in public.

On July 28, she was arrested for tampering with evidence, and three days later for allegedly flashing a machete to a victim on Fifth Avene, the sources said.
