Received a call around 10pm. Automated (badly recorded) voice said, "We're calling from Melrose Cooperative Bank to inform you that your bank account has been suspended. We're suspicious that a third party has been using it. Press 1 to reactivate your account." I didn't press 1.
The next day we checked with the bank, and they had around 1000 calls similar to this, so it's some sort of scam.
