Denver police officers responded to the 4800 block of Humboldt Street Friday on a report of a suspicious person dressed like a clown.
Police did not locate anyone who fit the description and no arrests were made.
The Ringing Brothers Circus has been performing at the Denver Coliseum since Sept. 30. DPD says the reported incident happened outside the circus.
The report comes after several weeks of incidents in which clowns seriously creeped people out all over the country.
In Greeley, police investigated a Facebook post threatening a shooting on Halloween that then morphed into fears clowns would carry out a shooting. The post was determined to be a hoax.
