A criminal lawyer has accused police of stalling an investigation into an officer who shot a woman in the eye with a Taser.

Queensland’s police commissioner is facing calls to explain why it’s taken five months to investigate an officer who shot a woman in the eye with a Taser.

Sheila Oakley was blinded in one eye when she was shot with the stun gun during a disturbance at her Logan house in February this year.

At the time, police said she threatened officers with a table leg that had nails sticking out of it.

Police quickly launched an Ethical Standards Command investigation into the officer who used the weapon.

But civil libertarian and criminal lawyer Terry O’Gorman says the woman is still waiting for any word on the outcome of that investigation.

He says it’s incumbent on Police Commissioner Ian Stewart to explain the extraordinary delay.

“Why has it taken since February? It’s now July. Why has it taken so long for such a straightforward issue to be investigated,” Mr O’Gorman told the ABC.

“It’s an unacceptably long time.

“The fact is that when police want to, (they) pump resources into high profile issues that they choose.

“In relation to complaints against police, they are given a low priority. They are deliberately delayed in the hope that journalists will forget it, and in the hope that complainants will jut get sick of the delay and give up.”

Police later said the investigation was still under way, with one further witness to be interviewed.

The final report is expected to be completed by July 30, police said.
