A brazen robbery crew ripped off nearly $13,000 in jewelry from three elderly victims in Brooklyn, Queens and Staten Island during a three-day spree last week, cops said. 

In the first stick-up, two strangers approached an 87-year-old woman outside a home at 18th and Cropsey avenues in Bath Beach, Brooklyn around 8:20 p.m. July 23 and wrapped a gold chain around her wrist, police said. 

They then grabbed both the victim’s bracelet – worth about $1,000 – and the one they placed on her, authorities said. 

The spree continued in Flushing, Queens around 8 p.m. July 25, when a duo pulled up in a white SUV to a home at 169th Street and 26th Avenue and blocked the driveway, cops said. 

The pair placed a necklace around the victim’s neck before grabbing it back – in addition to the $2,900 necklace she was wearing, police said. 

They then fled in the same white SUV, authorities said. 

The next day, on July 26, cops said two suspects approached a 76-year-old man in front of a Costco on Richmond Avenue near Forest Hill Road in the New Springville section of Staten Island. 

They handed the senior fake jewelry and watches before grabbing his Rolex watch and gold chain – as well as the fake accessories they had handed him, cops said. 

The watch and jewelry were worth about $9,000 in total, police said. 

No injuries were reported in any of the incidents.

Footage released by the NYPD late Tuesday shows a female suspect wearing a white shirt, long black skirt and bucket hat walking in a parking lot. A male suspect, wearing a black collared shirt, is shown paying at the counter of a deli.

Both the wanted woman and man remain at large.
