SAN BENITO, Texas (ValleyCentral) — The San Benito Post Office was under a bomb threat Tuesday morning, according to police.

Maximilliano Casanova, 38, was arrested and remains in custody on a charge of false alarm or report, according to the San Benito Police Department.

At about 10:15 a.m., police officers responded to the post office in San Benito after a postal employee called 911 to report that a man walked into the lobby and told them they were all in danger, according to police.
