DETROIT — The parent company of Detroit television station WXYZ says anchor Malcom Maddox is returning to work following an investigation into allegations the station ignored sexual harassment complaints against him.

The E.W. Scripps Co. says it completed an investigation into the allegations and found no basis for additional action against Maddox or others. Maddox told viewers Friday he’s made mistakes, but is renewing his responsibility to honor the station’s “policies and values.”

WXYZ placed Maddox on administrative leave Dec. 6 after allegations publicized by Detroit pastor the Rev. W.J. Rideout.

Scripps says in 2015 it determined Maddox engaged in inappropriate communications with coworkers that didn’t conform to company policy. Scripps says that at that time Maddox received corrective action, including a two-week unpaid suspension.

Maddox says he exercised “very poor judgment.”
