Domestic news agency ANSA said Balotelli, who was ruled out of his side's trip to Sampdoria on Sunday due to injury, had travelled to Liguria, on Italy's north-west coast, to watch his brother play in a football match.

The report said Balotelli later refused a photographer's request for a photo when he showed up at a restaurant with his fiancee Fanny Neguesha and some friends.

The party moved on to a nightclub, where the same photographer was waiting.

According to witnesses, Italy international Balotelli kicked the photographer after refusing another request for a picture.

The photographer called police and later accompanied them into the nightclub to identify the 23-year-old.

But Balotelli told ANSA: "I categorically deny being involved in the altercation, I was standing apart" from the incident.
