Australian-born entertainer and songwriter Rolf Harris was convicted of sex crimes on Monday.

A London court found Harris, 84, guilty of on 12 counts of indecently assaulting young girls, Reuters reports. The incidents occurred between 1968 and 1986 and involved Harris’s actions with four girls, some as young as seven or eight. A BBC report says Harris is now facing new allegations from 12 or more people who claim to be victims of his actions.

Harris is a prolific artist and musician who appeared in prime-time TV shows aimed at children, including one designed to combat the sexual abuse of children. He also entered the world of pop music, landing hits such as “Two Little Boys,” “Jake The Peg,” and “Tie Me Kangaroo Down Sport.”

Following his conviction, Australia moved to strip Harris of some of the honors bestowed upon him during his five-decade performing career. Harris will be stripped of his British Academy of Film and Television Arts fellowship, and there are calls for him to lose the honors bestowed upon him by the Queen. The Australian Recording Industry Association also decided to withdraw Harris from their Hall of Fame. He was inducted in 2008.
