City Wants To 'Ban' Clowns At Halloween

No clowns allowed.

A public advertisement for A US city's annual "Boo Bash" encouraging community members to "bring children in their favourite costume" has come with an express warning that clown costumes will not be allowed at the event.

The annual family-friendly party held at the Oak Park Community Centre has received backlash from some of the suburb's 30,000 residents who have questioned why other 'scary' costumes haven't also been banned by the council.

A statement from the city's recreation director obtained by the Oakland County Times said the council had put in the ban because many people have phobias and anxiety about clowns.

“In the past few years many clown costumes have been given a very scary and evil look,” an email statement to the newspaper reportedly said.

"Many scary and horror movies are centered around these types of characters. About 3 years [ago] there were national incidents in the news were people were dressing up as clowns and scaring people and in some cases assaulting them."

But the council has since attempted to reverse this decision releasing an official statement claiming "the City will not ban people with clown costumes... from participating in the Boo Bash Event."

"We are encouraging parents to use their best judgement given this is an event that caters to families and small children."

The terrifying 'Killer Clown' trend emerged globally in 2016 with people dressing up in clown costumes and stalking, chasing and threatening people in the streets.

Earlier this month police in the UK became worried the bizarre trend was resurfacing ahead of Halloween after reports two teenage boys were chased by a person dressed in a clown costume.
