A Democrat challenging Manhattan District Attorney Alvin Bragg in a primary this June vowed to get tough on subway crime – including targeting fare beaters – as he slammed the incumbent’s “poor” prosecuting record.

Civil litigator and former Bronx prosecutor Patrick Timmins said he’s aiming to ease the “tension” of straphangers after a series of violent incidents in the city’s transit system.

“No one’s getting a safe, comfortable, easy ride,” he argued in a recent interview. “We all know about the platform pushing, subway slashing, it’s at historical levels.”

Timmins, an uptown Manhattan resident, said cracking down on fare beating would prevent larger crimes underground.

“I understand ‘what’s a fare evasion here and there,’ but once there’s 20 of them by one person, then maybe something should be done,” he said.

“Most of the people who go down below the ground or even up to an elevated train and commit an attempted murder, a felonious assault, all those things are generally not people who swipe to get in.”

When Bragg, a former federal prosecutor, first assumed office, he quickly instructed staff not to prosecute fare evasion as part of a day one memo that faced backlash.

Timmins criticized Bragg for two prosecutions he dropped after fierce backlash that the accused were defending themselves — the case of bodega worker Jose Alba accused of fatally stabbing an ex-convict who shoved him around inside a deli and the case of Chinatown landlord Brian Chin who beat a homeless man after the vagrant attacked him with a weapon.

He also questioned the failed prosecution of Marine veteran Daniel Penny in the subway death of Jordan Neely, calling it a “toss-up maybe.”

“There’s been a lot of poor decisions by Alvin Bragg in those three-plus years,” Timmins said, adding later, “I’m a common sense Democrat.”

But Timmins also vowed to aggressively expunge the records of people who served their time with a main focus on drug offenses and non-violent crimes if elected.

“If you pay your debt to society, that should be really forgotten,” he said.

The first-time candidate has a lot of work ahead of him to knock off the progressive officeholder.

Bragg has a stark fundraising advantage over Timmins and more name recognition with the primary only a few months away.

And Bragg’s campaign pointed out the Broadway Democrats, a political club that counts Timmins as a member, overwhelmingly back the incumbent with close to a 100% of the vote.

“Patrick Timmins’ own neighborhood Democratic club endorsed Alvin Bragg virtually unanimously and here’s why: A prosecutor for more than two decades, Alvin has initiated a multi-pronged approach that has helped reduce shootings in Manhattan by 45%, invested in mental health outreach, stood up for victims, and held the powerful accountable,” a Bragg campaign spokesperson said.

“We know safety concerns are real, and we’ve got a lot of work ahead of us, but we are inspired by the support Alvin is receiving from Manhattan’s three Congressmembers, 25 neighborhood Democratic clubs, and people across the borough.”

Timmins’ campaign countered that Timmins hasn’t recently been active in the organization.

Former Democrat-turned-Republican Maud Maron, a former criminal defense lawyer, is seeking the GOP nomination for the district attorney post.
