Elderly twin sisters who were robbed and assaulted by a creep preying on old ladies received a get-well card and $500 donation Tuesday from a pair of cops, officials said.

The 71-year-old siblings had been on their way home from a Flushing bank when the suspect — wearing a surgical mask and yellow construction hat — followed them into an elevator in their apartment building and knocked them to the floor April 5, according to police.

One of the women had just cashed her $1,100 social-security check, and the perp swiped the dough.

A sister suffered a broken leg in the assault and is still recovering at New York Hospital of Queens.

The women’s plight prompted Officer Anthony Loverme with Community Affairs and Detective Kevin O’Donnell, both of whom worked the case, to buy a get-well-soon card from a local Rite Aid, fill it with the cash and go to the hospital to hand it over.

At the touching bedside scene were the two sisters and their aged mother.

Inspector Brian Maguire of the 109th Precinct said he was proud of his cops.

“Cops in New York City do things like this each and every day. I love the fact that my officers took it upon themselves and they rose to the occasion,” he said.

Suspect Salvador Morales,58, was arrested after detectives in the 60th Precinct were able to help identify him from similar burglaries he pulled off in Coney Island in Brooklyn wearing the same mask-and-hat get-up, police said.

Morales has at least 10 prior arrests for burglaries dating back to 1989.

On Christmas Eve, he claimed to be an upstairs neighbor in a Brooklyn building and burglarized an 89-year-old woman’s home, cops said.

Morales promised the woman he would fix a pipe in her apartment that was leaking water into his supposed pad downstairs, cops said. He entered the apartment and stole $2,200 in cash, gold rings and a bracelet, police said.

On Jan. 19, he pulled the same stunt on an elderly woman in the same Brooklyn building and stole $170 in cash and a ring and earrings, cops said.

He was charged with burglary, Grand Larceny and Criminal possession of stolen property for those cases, cops said.

He has been charged with burglary, robbery and assault in the incident involving the elderly sisters.
