(CNN) "The Royals" creator and showrunner Mark Schwahn has been fired from the series following a suspension in November after colleagues accused him of sexual harassment

"We have concluded our investigation and Mark will not be returning to 'The Royals,'" Lionsgate, the company which produces the series, announced in a statement obtained by CNN on Thursday.

Schwahn's suspension last month came just days after a group of 18 actors and crew members who worked with him on his previous TV series, "One Tree Hill" came forward with accusations of sexual harassment in a joint statement

"E!, Universal Cable Productions and Lionsgate Television take sexual harassment allegations very seriously, investigate them thoroughly and independently, and take appropriate action," the three companies said in a joint statement given to CNN at the time.

Alexandra Park, who stars on "The Royals," echoed the concerns voiced by the former "One Tree Hill" staff members, saying she, too, had "been exposed" to Schwahn's "reprehensible behavior."
