According to The Guardian, the sightings were suspected to be a PR stunt for the upcoming release of a new movie for Stephen King's 1986 horror novel It, featuring the infamously creepy clown called Pennywise.
This prompted other people to dress up in clown attire, terrorizing people and sometimes attacking them.
Fox News reported that a Pennsylvania teen was reportedly stabbed to death during a fight that broke out after someone appeared with a clown mask.
The clown debacle also made its way to the UK, with The Independent reporting that many people in clown clothes chased a boy "younger than a teenager" in Suffolk.
During this time, McDonald's released a statement to CNBC about their decision to ditch their famous mascot, noting that they were being "mindful" of the situations occurring and would cease "Ronald McDonald's participation in community events for the time being."
And the UK McDonald's also made a statement noting that the clown won't appear in their advertising but is "still very busy working for us."
Ronald McDonald can still be seen in some restaurants in places around the world, although he is mostly nowhere to be seen.
American weather presenter and actor Willard Scott was the original portrayer of Ronald McDonald from 1963 to the early 1970s.
