Man pleads not guily to urine switch

A 26-year-old man has pleaded not guilty to fraud charges following plans to tamper with a urine test to score a mining job.

ABC News reports the man is due back in court next month along with other people involved in the plan.

Last month a joint operation between WA Police and the Corruption and Crime Commission uncovered a plot to switch urine tests to beat the mining industry's strict drug testing regime.

It's alleged a WA Health Department official and senior members of the Gypsy Joker gang are also involved in the plan.

The Health Department official has been charged with corruption and has already faced court in Tom Price.
