The call to Barrie Police just before midnight on Thursday from a Barrie Transit bus driver described a suspicious person seen going behind an elementary school on Little Avenue.
Officers were told the male was dressed in black, wearing a mask and carrying a backpack.
Police located the youth and discovered he was in the process of making a YouTube video.
"It was obvious that there was nothing criminal in nature taking place and after speaking to the involved youth, he quickly realized that the way he was dressed, and the time of the night, created a level of concern that prompted the police response," according to police news release on Friday.
