DETROIT, MICHIGAN — A video of a creepy clown hitching a ride on the back of a Detroit city bus has gone viral, and the city’s transportation department is not amused. <br /> <br />The footage was captured by the dashcam of an unidentified driver, who probably never expect to see a clown clinging to the back of a bus — even in Detroit. <br /> <br />The Detroit Department of Transportation has forwarded the video to the police, who are investigating. <br />The motivation and the identity of the clown remains unclear, according to UPI, one YouTube commenter noted that the costume is similar one seen in a video posted by Instagram prankster @g_dulla_mulla. <br /> <br />That video ends with the prankster dressed in a clown suit and clinging onto the back of a Detroit city bus. Unfortunately, the video was removed from Instagram on Tuesday morning and the account appears to have been closed.
