They said the trio, understood to be two men and a woman, were kicked out of their hotel in Santa Ponsa after the heated altercation.
They were nabbed after hotel staff identified them as the aggressors.
The woman allegedly punched one of the officers in the chest after showing her middle finger at police when she was being detained.
The three Brits were later released but an investigation into the assault is ongoing.
They were forced to find another holiday accommodation after the incident and remain banned from the hotel.
