Waterville police say seven young adults and youths have been arrested after Molotov cocktails were set off in a former Boys and Girls Club, shot on video and posted on the video-sharing Web site YouTube.

Police said the suspects broke into the building through a window, made Molotov cocktails and then set them off. Police seized a video showing the group making and throwing the devices, which exploded and caused fires with flames going as high as 20 feet.

Police said the video, which has since been taken off YouTube, showed the faces of the suspects as well as text naming those who were pictured. Each of the seven, who range in ages from 14 to 20, is charged with arson and burglary.
