He kicked one of the tourists, a 22-year-old man, in the buttocks and three times in the face. When a woman intervened Tucker lashed out at her also, striking her in the forehead and causing her to fall to the ground.
When Tucker was arrested he denied the assaults and claimed he had been punched.
Defence lawyer Liz Bulger said Tucker told her it was a "two-way incident" and the police summary of facts did not reflect that.
