The Doctor Blake Mysteries is set to return without lead star Craig McLachlan.

Earlier this year the Gold Logie-winning actor was accused of indecent assault, sexual harassment and bullying, allegations McLachlan has vehemently denied.

A joint investigation between Fairfax Media and the ABC focused on McLachlan's alleged behaviour during the 2014 production of the Rocky Horror Show. However, a Doctor Blake crew member later came forward to say McLachlan's behaviour on the set of the beloved TV show "looked like sexual harassment".

McLachlan's co-star Nadine Garner defended the show's "lewd" on-set behaviour. An investigation by the show's production company, December Media, cleared the actor of any misconduct.
