Details of those incidents and changes to storage facilities have not been revealed as police are concerned it will alert criminals about where and how evidence against them is stored.
Criminal bar association president Tony Bouchier said lawyers' clients frequently complained of getting broken phones and electronics back from police storage.

The national manager of response and operations Superintendent Chris Scahill told Fairfax the review was proactive and identified opportunities for improvement.
