Chris Hardwick will return to AMC next month as the host of “Talking Dead” and the second season of “Talking With Chris Hardwick,” according to a statement released by the network on Wednesday. Mr. Hardwick had been accused of both physical and emotional sexual abuse by Chloe Dykstra, an actress and ex-girlfriend, in a post on Medium last month, over a three year relationship.

“Following a comprehensive assessment by AMC, working with Ivy Kagan Bierman of the firm Loeb & Loeb, who has considerable experience in this area, Chris Hardwick will return to AMC as the host of ‘Talking Dead’ and ‘Talking with Chris Hardwick,’” an AMC spokesman said in a statement. “We take these matters very seriously and given the information available to us after a very careful review, including interviews with numerous individuals, we believe returning Chris to work is the appropriate step.”

AMC did not elaborate beyond its statement.

Ms. Dykstra, who did not respond to a request for comment, did not name Mr. Hardwick specifically in her Medium post, but gave enough detail that many readers were able to deduce who she was referring to. She wrote that Mr. Hardwick had decreed, among other things, that she “was to not have close male friends” unless they worked together and that she was not to speak in public. She also said Mr. Hardwick pressured her to have sex when she didn’t want to.

“During all of this I lost myself, both mentally and physically,” Ms. Dykstra wrote. “I lost 15 lbs. within weeks, started pulling out my hair (and had to get extensions regularly to hide it). I generally stopped speaking unless spoken to while with him, drifting through life like a ghost.”
