Stephen Sideras pleads not guilty to commercial drug trafficking after a search of his home and work

An alleged dealer will face trial accused of running a secret drug lab from his workplace after kilos of marijuana and $13,000 were uncovered.

A man will face trial next year after a search of his home and work allegedly uncovered a commercial drug operation.

Stephen Paul Sideras, 29, appeared in the District Court last week and denied trafficking kilos of marijuana, which police allege was packaged for sale.

Barossa Police and CIB detectives, with the assistance of Police Drug Dog Georgie, conducted co-ordinated searches at a residential address in Lewiston and a Smithfield business on November 25, last year.

Police allegedly seized more than $13,000 and 2.8kg of marijuana that they allege was ready for sale.

Police also discovered a cannabis oil extraction laboratory in one of the offices.

Jacinta van den Berk, and Mr Sideras’ partner as listed on Facebook, was initially jointly charged with him.

However, a prosecutor told the court in June they would be withdrawing all charges against her and only proceeding against Mr Sideras.

In the District Court last week, Mr Sideras, pleaded not guilty to trafficking in a large commercial quantity of a controlled drug, drug trafficking and manufacturing a controlled drug for sale.

The court heard the trial would likely take four days and it was listed for late next year.

Chief Judge Michael Evans also allowed a bail variation so Mr Sideras could travel interstate.
