Zoo Miami abruptly closed Saturday afternoon after a bomb threat for the second day in a row, according to a social-media post from the zoo.

More than 100 cars were stuck in traffic on the road leading out of the attraction.

The zoo also had a bomb threat on Friday afternoon. The zoo closed after “an anonymous phone call reporting a bomb threat,” the facility said at the time.

The sheriff’s office told the Miami Herald that the Friday call was likely a hoax, but deputies were nevertheless checking the area. The office has yet to respond to the Herald’s requests for information about Saturday’s incident.
