The Madison Police Department is warning residents about fraudulent callers claiming to be from Madison police.

According to a release from MPD, they have seen a series of calls in which a woman with an accent claims to be from MPD and tells residents they must pay a ticket within 45 minutes or face a warrant for their arrest.

In a few cases, victims have been told to call 713-357-6055 and ask for Tom O'Brien. According to the release, the name and number are fake.
