WA prison guard charged with corruption

A 50-year-old West Australian prison guard has been charged with corruption.

Police said on Friday the woman had been charged as part of Operation Ulysses, which is investigating serious offences in the state's prisons system.

She has been bailed to appear in the Midland Court of Petty Sessions on June 13.

The charge follows the jailing in April of a chef instructor at Greenough prison near Geraldton, who smuggled cannabis and a mobile phone to a bikie inmate.

The Operation Ulysses taskforce, which was set up last year, has recommended the re-establishment of a police prisons unit after finding WA jails were awash with drugs.

The unit was dissolved almost 10 years ago.
