BOARDMAN — Multiple residents have reported fraud on their credit cards or bank accounts since Jan. 1, having been bilked collectively out of roughly $10,000.

On Friday, a resident in the 200 block of Indianola Road reported that a Citizens Bank check she had written for $40 on Dec. 22 was found to have been altered when she checked her bank statement. The police report states she told police the check’s date was changed to Dec. 28 and the amount altered to $4,350. The report states the check was deposited using the mobile deposit feature. The woman said the check was placed in her home mailbox or the standalone mailbox on Simon Road.

Police took a similar report on Saturday, when a Redtail Hawk Drive resident came to the station to report that a check she wrote in early December had been stolen and altered. The woman wrote the check for $54.74 to pay her Capital One bill and put it in the mailbox in front of Dollar Tree in the Boardman Plaza.

Recently, she received a notice from Capital One that she had an outstanding balance and a late fee. The police report states that when she asked Huntington Bank about it, they showed her the check with the same date and check number, but it was written to someone she did not know and the signature was not in her handwriting. The amount had been changed to $899.

Also reported on Friday, a woman had $425 stolen from her Green Dot bank account on Dec. 23, and her $813 paycheck stolen from her Wisely account on Dec. 31. The woman said she is locked out of both accounts because of the banks’ internal investigations into the fraudulent activity and could not provide more detailed information at the time of the report.

On Sunday, police responded to Meijer, where a woman reported that she had last used her Discover card on Friday to buy gas at a station on Midlothian Boulevard. But on Saturday night, she received a text notification from Discover that her card had been used twice at Meijer, for $498 and $41.39. The report states that the manager at the store told her the purchases were likely caught on camera but she would need to file a police report first. She said the card also was used at several stores inside the Southern Park Mall — Crown Jewelers, SQ Sole Gallery, Zumiez, Diamond World and a vending machine — for a total of $930.17.

Police took another report on Sunday, at the station, from a Boardman Boulevard resident. The woman informed police that she had received notifications from Citibank that morning about possible unauthorized activity on her card. The report states that when she checked her account online, she found that someone had used her card 56 times over the previous 24 hours or so, spending roughly $3,000. The report does not state where the purchases were made.

Another suspicious incident was reported Friday, although the potential damage to the victim is unknown at this time.

The police report states that the caregiver for a woman in the 4500 block of Waseka Lane reported that her client gave the client’s social security number to a man over the phone. When she took the phone and asked who the man was, he said in a foreign accent that he was a supervisor with Medicare and hung up when she asked his name.
