After reports of 'killer clowns' across the USA, it appears the craze has now come to the UK with yet another sighting - and this time in London Brunel University .
An alarming image has emerged of a clown in Uxbridge holding what appears to be a chainsaw on the University campus, the latest in a string of events which have wreaked havoc across the country.
In a statement, Security Operations Manager Terry Vass said: "Someone dressed as a clown and carrying what appeared to be a chainsaw was seen on the campus on Saturday night.
"Although we can't confirm whether the chainsaw was real or not, we take such incidents and our students' safety extremely seriously.
"Brunel's campus is patrolled by security teams 24 hours a day and is monitored by more than 400 CCTV cameras, which we are now examining.
"We will continue to work with police to identify the individual responsible."
The Metropolitan Police said they have not received any reports of incidents involving clowns in London as yet, but urge people to come forward if there are any incidents.
There have been a number of reported clown sightings across the UK, with people dressing up as clowns and scaring people.
