Nassau County police released information Monday about four separate grand larceny scams that occurred in April.

The first incident happened on April 6 in Farmingdale when detectives say a 69-year-old woman received a call from someone claiming to be an Apple employee. The caller instructed the victim to withdraw all of her money from her bank account and travel to Connecticut to transfer it into multiple cryptocurrency accounts in order to keep it safe.

The victim made several trips, transferring over $500,000 from her account. She was informed by her bank that she was scammed and contacted police.

On April 13, detectives say a 67-year-old man met an unknown person through Facebook who advised him to contact another person about a government program he could be eligible for. The victim contacted that person and was advised to send money to apply for the false program.

The victim made several transactions for a total of several thousand dollars before realizing he was scammed and contacted police.

Detectives say the third incident happened on April 14 in Bethpage when an 84-year-old woman received a call from someone falsely claiming to be a lawyer for her grandson who was arrested. The caller allegedly informed the victim that her grandson needed $9,800 to be bailed out and instructed her to withdraw the money and return home.

A short time later, the victim received another call instructing her to go outside her residence to a parked car. A man was waiting and took the victim's money and fled the scene. The victim later realized it was scam and contacted police.

The final reported incident happened on Wednesday in North Merrick when detectives say a victim was contacted by someone saying he was from PSEG Long Island. The suspect told the unidentified victim that the account was two months late on payments and instructed him to Zelle a total of $2,998.13 to an unknown number on her Bank of America account.

The victim transferred the money, then became suspicious and contacted police.

The American Association of Retired Persons says more than 2,000 people in the New York metro area last year and says the number is probably higher because many scams don't get reported.

State Director of AARP New York Beth Finkel says senior can protect themselves from scams by not playing nice with potential scammers.
