The New York Police Department arrested more than 100 Harlem gang members Wednesday in one of the largest gang crackdowns in New York City's history. 

The police arrested the gang members after investigating the murder of 18-year-old Tayshana "Chicken" Murphy, according to The New York Post. 

More than 400 police officers dressed in body armor raided the Manhattanville and Grant Project Houses near Amsterdam Avenue and West 125th Street around 5:30 a.m. Wednesday. The raid was called "Operation Money Grant."

Police arrested 103 people, and 41 of those arrested had already been in jail on other charges. Police had 29 search warrants to sweep the houses and make the arrests. 

The suspects were accused in at least two murders, 19 non-fatal shootings and 50 other shooting incidents, according to CBS Local. 

NYPD Commissioner Bill Bratton addressed officers before the raid at the 33rd Precinct station house. 

The gang members who were arrested are part of the gang allegedly responsible for a turf war that resulted in the fatal shooting of Murphy, a rising basketball star. The point guard from Murry Bergtraum High School was killed at Grant Houses on Sept. 10, 2011. She was ranked as the 16th best point guard in the nation in her respective graduating class by ESPN. 

Authorities were prompted to probe the gangs due to Murphy's murder. Police investigated the gangs since her death in 2011, and finally ended the investigation Wednesday. 

Robert Cartegena, a gangster who lived at the Grant Houses, was convicted two months ago for Murphy's murder, as well as for burglary and criminal possession of a weapon. He was sentenced to 25 years to life in prison. 

Tyshawn Brockington, 24, was also convicted in the case, and was similarly sentenced to 25 years to life behind bars. 

According to prosecutors, Cartagena and Brockington were overheard saying that they were going to "smoke" (read: kill) someone from Grant Houses on the day of Murphy's murder. Murphy was shot three times, and later died. 

Brockington and Cartagena went to South Carolina after the shooting, where they were arrested. 

Many of the gangsters laughed while police hauled them out of their homes.

One shouted, "Happy Stack Day!" as he was led out, in a reference to his gang, the "Staccs."

Members of two other gangs, the "Make it Happen Boyz" and "Money Avenue" were also arrested in the raid. The raid was led by the NYPD's Organized Crime Control Bureau, along with Housing, the Narcotics Division, the Manhattan Gang Unit and investigators from the Manhattan District Attorney's Office. 

A grandmother who lives at Grant Houses told CBS Local that she is happy the gang members were arrested, but does not think it will mitigate the violence in the area. 

"I worry about my grand kids out here playing in the park. Anyone could get hit when they shoot," the 57-year-old said, pointing to the place where "Chicken" Murphy was shot.

"There are more of them, just waiting to fill their shoes," she said in reference to the gang members.

"It's just sad. All of this mess should have been over when that poor child [Murphy] was killed," she added.
