SA man accused of dealing meth near school

A man has been accused of dealing methamphetamine near a school in South Australia's Riverland.

The 49-year-old was one of three men charged with drug trafficking after the methamphetamine was found in a car northeast of Adelaide on Saturday, police say.

The two men in the car, 25 and 31, will appear in Berri Magistrates Court on Monday and the 49-year-old will appear in court in January.

No students appear to have bought methamphetamine or been involved with the trafficking.
