NEW YORK — A coalition of police unions is backing Liz Crotty for Manhattan district attorney, NY1 has learned.

The NYPD sergeants, lieutenants, captains and detectives unions said Thursday they're endorsing Crotty, who has staked out an unambiguous tough-on-crime stance in the crowded field of Democrats vying to replace outgoing DA Cy Vance.

Crotty is a former Manhattan assistant district attorney who’s spent twice as long as a criminal defense lawyer.

In a virtual NY1 debate earlier this week, Crotty noted spiking crime rates and said, “I am the candidate who from the beginning of my campaign has talked about public safety.”

The rank-and-file police union, the Police Benevolent Association, or PBA, is not among those who endorsed Crotty on Thursday.

Separately Thursday, Manhattan district attorney candidate Tahanie Aboushi filed a notice of claim on behalf of a protester violently arrested by the NYPD in late April. Aboushi, a civil rights attorney, says the woman’s rights were violated when her private body parts were exposed during the scuffle.

As of the last campaign finance filing, Crotty had raised the least amount of cash of any of the eight Democratic candidates but more than 70% of her donations came from Manhattan.

The primary’s top fundraisers are Tali Farhadian Weinstein and Alvin Bragg, both of whom were targeted by their rivals in the cross-examination portion of the NY1 debate.
