A married former director of the Centers for Disease Control and Prevention — and onetime city health commissioner — was arrested Friday for allegedly grabbing a woman’s behind in his Brooklyn apartment 10 months ago, police sources said.

Dr. Thomas Frieden, 57, was charged with misdemeanor counts of third-degree sexual abuse and forcible touching, as well as harassment, a violation, for the alleged groping of the 55-year-old woman.

The woman, a feminist activist, was described as a close friend who had known Frieden and his family for more than 30 years. They were not believed to be romantically involved.

She and another couple were at his apartment on Montague Street in Brooklyn Heights for a get-together on Oct. 20, 2017, and he allegedly squeezed her behind as the group was getting ready to leave at around 11 p.m., sources said.

The woman filed a report about the incident on July 7.

Frieden was arrested at 10 a.m. Friday after turning himself in at the NYPD’s Special Victims Division in Prospect Heights. He faces up to a year in jail if convicted.

He looked glum and didn’t answer reporters’ questions as he was walked by two detectives into a squad car with his hands cuffed behind him.

In court, he pleaded not guilty and a judge issued an order of protection on behalf of the woman before releasing him on his own recognizance.

“This allegation does not reflect Dr. Frieden’s public or private behavior or his values over a lifetime of service to improve health around the world,” his spokeswoman said.

The married dad of two currently heads Resolve to Save Lives, a $225 million health initiative by nonprofit Vital Strategies that is funded by the charities of former Mayor Mike Bloomberg and others.

Vital Strategies President and CEO Jose Castro said Frieden was upfront about the allegations back in April.

“I have known and worked closely with Dr. Frieden for nearly 30 years and have seen firsthand that he has the highest ethical standards both personally and professionally,” Castro said.

“In all of my experiences with him, there have never been any concerns or reports of inappropriate conduct.”

As the head of the city’s Department of Health and Mental Hygiene from 2002 to 2009, Frieden was best known for banning smoking in bars and restaurants as part of a campaign that cut the number of smokers in the Big Apple.

He also banned trans fats in food, pushed for calorie information on menus and supported the distribution of free condoms.

Frieden went to Oberlin College in Ohio, where he met his wife, Barbara Chang. The couple has two children.

He was appointed to the top post at the CDC in 2009 by President Barack Obama, who called him “an expert in preparedness and response to health emergencies.”

With the CDC, which is based in Atlanta, Georgia, he helped stem the Ebola epidemic and stepped down as part of the turnover to President Trump’s administration.

Frieden announced in September 2017 that he had moved back to New York City to head Resolve to Save Lives.

Chang did not return a message.
