A POLICE probe is under way after two men who work at a laboratory used by police in Greater Manchester to test drug samples were arrested.

The men, 47 and 31, were arrested on suspicion of perverting the course of justice.

The two suspects have been bailed until next month as investigations continues.

A spokesman for Greater Manchester Police said: “GMP have been asked to conduct a criminal investigation into forensic results issued by Randox Testing Services (RTS).

“Randox Testing Services has provided forensic services to police forces, including GMP, for the past two years.

“The organisation is being fully co-operative of the investigation.”

The allegations relate to drug tests analysed at its Manchester office.

In a statement published on the RTS a spokesman said: “A number of toxicology results, which are part of due legal process, have been compromised.  

"Randox Testing Services are working tirelessly to fully assess the impact and implications for each case.

“Where possible, when viable, samples will be re-run to provide robust, uncompromised results.”

He added: "There is no question mark over the RTS quality system or the robustness of our practices and procedures."

It is believed hundreds of cases could be reviewed as a result of the investigation.
