The letter was posted online and on Facebook yesterday after several threats were made. 

The Flushing school district has released a statement about alleged clown sightings and threats, and has found that they can be traced back to a student, posting on social media. They're working with Flushing PD right now to investigate, and while they've received calls from concerned parents about a possible lockdown, there is no credible threat.

The letter also tells parents to remind their kids about the dangers of social media, and that some of the kids making these threats have been arrested and charged with felonies.

This whole thing is ridiculous. There's a lot of things we need to be afraid of in this world, but clowns aren't one of them.
