According to the Straits Times, last weekend five teenagers were detained in the northern border city of Mexicali after they dressed as clowns and frightened people by chasing them with bats. In the central city of Queretaro, five others were detained police received complaints due to their devilish clown appearance.

As reported by the news portal, an Argentine clown who goes by "Fluorescent Plug" said "I don't see anything funny about it," while participating the Convention wearing giant trousers. "Clowns make people laugh and happy..It's not just painting your face," he said.

Moreover, Tomas Morales, president of the Brotherhood of Latino Clowns, expressed concern about the craze and said that it could be dangerous.

"If (people) see in the news that we are evil, they can take a machete or a gun and kill a clown," Morales said, as reported. He also requests the media not to invent cases of clowns that cause terror.
