SA drug trafficking accused turns self in

One of South Australia's most wanted men has turned himself in to police and will face court on drug trafficking charges.

San Sem, who was charged in 2010 with manufacturing methylamphetamine and drug trafficking but failed to show for court, was arrested on Thursday morning after presenting at Elizabeth police station.

He was taken into custody and was expected to face Adelaide Magistrates Court later on Thursday.

Sem was one of two South Australians targeted in Operation Roam, a campaign aimed at finding Australia's 19 most wanted fugitives.

Robert Gordon Pollybank Gee, who police believe was the ringleader of a national illicit drugs network, remains at large.

Gee failed to appear for his 2011 trial and his whereabouts are unknown.

Operation Roam will run from August 15 to 26, with the full list of fugitives available at fugitivehunt.com.au.
