Named in Police Report
As Alleged Cell Phone Snatcher
Sources tell TMZ ... a photog named Timothy Jackson filed the report, citing "criminal damages" over an incident that went down Monday night.
Jackson told cops he was with a group of photogs ... when he began to shoot Brand with his iPhone from his car. Jackson claims Brand flipped out, wrestled the phone out of his hand ... and then Nolan Ryan'd it at a nearby building, shattering a glass window.
The pap immediately filed a police report. No word if he got his phone back.
Calls to Brand's rep have not been returned.
Law enforcement tells TMZ ... cops are investigating the incident and would like to speak with Brand ASAP.
