AN unarmed mentally disturbed man who was Tasered by WA police 13 times in several minutes was shot with the device a second time by prison guards a week later.

The first incident in the East Perth lock-up was caught on closed-circuit footage and revealed in a report released yesterday by the state's Corruption and Crime Commission.

The WA Department of Corrective Services last night confirmed to The Australian that the man was Tasered again a week later when officers were moving him from his cell.

In June last year, Queenslander Antonio Galeano, 39, died after he was Tasered by police 28 times, while last year Ronald Mitchell, an Aboriginal petrol sniffer from the outback West Australian town of Warburton, burst into flames after being shot with the device when he threatened to throw petrol at police.
