A 55-year-old man has been arrested on suspicion of three counts of sexual assault and remains in custody for questioning.
The arrest follows allegations that a woman had been sexually assaulted at a tattoo parlour in Salford last month.
A total of three victims are now being supported by specialist officers.
Constable Simon Judd, of GMP’s City of Manchester division, said: “Sexual offences often have a lifelong impact on victims and Greater Manchester Police is committed to investigating reports thoroughly.
“Whilst a man is in custody, our investigation is ongoing and I would encourage anyone with information that might help us with our enquiries to get in touch with us as a matter of urgency.
“I would like to reassure anyone who comes forward that information will be held in the strictest confidence”.
