Manchester police arrested two people suspected of manipulating the results of the laboratory tests, including the tests made within the framework of the judicial examination by the request of the police, reports BBC. Now it is necessary to review the results of 484 tests, submitted in November 2015. Two men, 47 and 31, are now being invested.

The data of the alcohol tests, including tests for drivers, was not manipulated, since the tests were made in another lab. The criminals changed the results only. That is, they had nothing to do with the biological material. There are no complaints about the equipment or software errors.
