A spokesperson for Greater Manchester Police said: "We can confirm we have received reports of misconduct in the workplace against a serving GMP officer, who has been suspended following these allegations.
"An investigation is underway by our Professionals Standards Branch and a 47-year-old man has been arrested on suspicion of sexual assault as part of our enquiries.
