If you've used your credit or debit card at a Chipotle Mexican Grill in the last few months, you definitely want to keep reading.

According to the Maine State Police, Chipotle is investigating a "unauthorized activity" on their payment processing system that may affect customers who used credit / debit cards at their establishments between March 24th and April 18th.

The company is still investigating and will notify customers when they know more.

If you see unauthorized purchases on your card, no matter how small the amount, notify your financial institution.
