Another Northern Ireland school was put in lockdown yesterday after a warning that a so-called 'killer clown' was on his way.
Holy Trinity College in Cookstown closed its gates yesterday after reports that a 'killer clown' was going to the school, police said.
The school asked the police to keep a watch over it, but no 'killer clowns' were spotted.
Earlier this week, armed police guarded over two Ballymoney schools yesterday after knife-wielding clowns threatened to pay a visit.
It came just days after a knife was brandished by a group of teenagers dressed as clowns in the town's Riverside Park.
Last Friday, a school in Coleraine shut its doors after reports that 'killer clowns' were about to strike.
The PSNI has issued warnings on Facebook that while 'killer clown' costumes are not illegal, crimes could still be committed, such as common assault - any act which intentionally or recklessly causes another to fear immediate, unlawful violence.
Meanwhile, McDonald's says its mascot Ronald McDonald is keeping a low profile at the moment.
The fast food giant told US media that it is being "thoughtful in respect to Ronald McDonald's participation in community events as a result of the current climate around clown sightings in communities".
