Manhattan District Attorney Alvin Bragg said he is preparing to present charges to a grand jury Tuesday related to the Jan. 27 assault of police officers.

In a statement Saturday, Bragg also said that after reviewing the latest surveillance video, some of the most culpable individuals in the assault have yet to be identified.

"We are working hand in hand with the NYPD to find and hold them accountable for their despicable acts," Bragg said. "We are simultaneously preparing to present charges to the Grand Jury on Tuesday and will update the public as soon as legally permissible. We will not rest until every person who assaulted a police officer in this awful attack is held accountable."

The assault on two NYPD officers happened outside a migrant shelter in Times Square last Saturday. Surveillance video shows a group of about a dozen men kicking and punching the two cops who were trying to disperse the disorderly crowd.

Police said they are still searching for some of the 13 suspects believed to have been involved. Seven people were initially arrested, and five of them were released without bail.

According to reports, some of the men got on a bus and fled to California.

One suspect is in custody on Rikers Island with bail set at $15,000.

The NYPD says the suspect at Rikers Island was at the center of the beating. Prosecutors say they need more time to determine the role of the other suspects.

All of the suspects face assault charges. Bragg has faced criticism for releasing the individuals, including from New York Attorney General Letitia James.

"Bail should have been set on those individuals. It was a serious felony," James said Friday.

NYPD commissioner Edward Caban also released a statement Saturday, saying the assault was "an attack against our entire society."

"We will work tirelessly with the office of the Manhattan District Attorney to identify and arrest every person who participated in this event," Caban said.
