According to the police report, freelance photog Robert Martinez was snapping some shots of Derek and his family outside the Yankee star's Florida home -- and Derek's dad was none too pleased.
Martinez claims Charles Jeter pushed him away while he was taking photographs, and then yanked him back by his jacket collar -- injuring the photog's neck and back.
The trauma must have been minimal -- because as we first reported, Martinez was back on the job a week later ... stirring up more trouble at Hulk Hogan's beachfront nuptials.
