The Miami-Dade Police Department is investigating a social media post that warns of a mass shooting at a local movie theater.
A Twitter account with the handle "Seven_JC7" posted a tweet on May 20 saying, "There will be a shooting massacre in Florida in the city of Miami. That will occur at AMC Tamiami in 13 days."
The tweet goes on to say the shooting will be "carried out by the perp that goes by the name, Erin Blok."
The same account makes numerous claims with similar language of shooting massacres at a school in Pittsburgh, a school in North Dakota, and more. The account names a different "perp" each time.
"Although credibility of the online threat remains undetermined, we are investigating and taking precautionary measures out of an abundance of caution," Miami-Dade police tweeted.
Police also caution people to remain vigilant and to say something if you see something.
