A kindhearted NYPD officer was caught on camera helping a blind woman hail a cab in the rain on a city street, the video shows.

The do-gooder in blue, identified only as transit Officer Swartz, had no clue he was being filmed when he offered up the “random act of kindness,” according to a tweet posted Monday by NYPD News.

“When NYPD Officer Swartz spotted a blind woman in the rain, he knew he had to help,” the video notes. “He hailed her a taxi and got her out of the rain in no time.”

The officer is then shown helping a woman with a white cane into the cab before it drives away.

“Every day our cops carry out random acts of kindness. They don’t do it for the recognition, they do it because it’s their calling. @NYPDTransit,” the tweet says. “Thank you for showing what it means to be an NYPD cop.”

The officer’s full name and location of the incident were not immediately clear.
