The FBI is investigating an ATM scam in Oak Bluffs, on Martha’s Vineyard, that has already affected 150 people.

During a six or seven week period over the summer, customers who used an ATM near the Flying Horses carousel may have had their personal banking information stolen.

Martha’s Vineyard Savings Bank customers represented 130 victims who had $140,ooo withdrawn from their accounts.  Bank of America said 37 of its customers lost $21,647, according to Oak Bluffs Lt. Timothy Williamson.

These illegal transactions took place between Sept. 1 and Sept. 5, in Chicago, Indianapolis, and New York. Once victims and their banks became aware, their cards were cancelled.

So far, about $160,000 has been stolen by two suspects, police told the Boston Globe. However, victims have reported more than $180,000 stolen, according to the AP. Williamson expects that number to grow.

Police alerted the public about the scam on Facebook Wednesday night, according to the Cape Cod Times.

The scam was executed by two men who placed a device on the card reader of an ATM, and used a small camera to record personal I.D. numbers. The device reads the card as it’s being scanned by the ATM and stores all of the personal information. This information can then be transferred to blank cards then used to withdraw money from ATM’s.

Williamson suggests examining an ATM and covering the PIN pad with your hand to avoid this scam.

Police have released photos of the suspects that outlets have not released.

Both men are in their 20’s, of average height, and slim. One wore an Armani Exchange T-shirt with A/X MILAN NYC on it, police told Boston.com.
