SAN DIEGO–Authorities are investigating a Craigslist post that reportedly threaten to carry out similar attacks of last week’s massacre at a gay Orlando nightclub.

The post, which has been taken down, featured an image of person firing a handgun. A message was written by an anonymous person, “Orlando was long overdue. Cleanse your community of the filth that gives decent gay men and women a bad name. Those people were walking diseases, bug chasers, and thank god for AIDS and 9-11 and now Orlando. San Diego you are next…”

San Diego station 10 News first reported on the post on its Tuesday’s evening’s broadcast. The report alerted San Diego police and federal authorities to search for the person behind the post.

San Diego Police Chief Shelley Zimmerman released a statement on the case:

“The San Diego Police Department is aware of a recent post on Craigslist that has since been removed. We are investigating collaboratively with our law enforcement partners. The latest information remains, there are no known credible threats to the San Diego region. As always, we encourage our community if they see something, hear something, or know something, to say something.”

Authorities are continuing their investigation.
