York Regional Police did not release the charges against Stuckless when they arrested him early Wednesday morning, the Toronto Star reported.
Stuckless, 64, was arrested Friday and charged with nine counts of indecent assault, five counts of gross indecency and one count of sodomy.
In announcing the charges, police said five new male adults had accused Stuckless of sexually assaulting them in the late 1960s and 1970s.
He was also arrested in February by Toronto police and charged with six counts of indecently assaulting a male, one count of assault and one count of possession of a weapon or an imitation.
Stuckless was convicted 15 years ago of raping boys while he worked at a Toronto sports arena.
