In May 2020, prosecutors in California charged Mr Roiland, 42, with two charges of domestic battery with corporal injury and false imprisonment by menace, violence, fraud and/or deceit, of an unidentified woman who was living with him at the time.

A police complaint said the incident, which allegedly occurred on or around 19 January of the same year, resulted "in a traumatic condition" for the woman.
His lawyer said in a statement that his client was "innocent", adding: "We look forward to clearing Justin's name and helping him move forward as swiftly as possible."
Mr Roiland appeared at a pre-trial hearing earlier this month and is set to return to court in April, ahead of a trial. He could face up to seven years in prison.
He created the anarchic animated sitcom with Dan Harmon in 2013, and it won the Emmy for best animated programme in 2018 and 2020.
