Scammers in Bournemouth and Poole are costing local businesses tens of thousands of pounds by hijacking voicemail systems to make them dial premium rate numbers.

Dorset Police is warning all residents to ensure they have a secure password for their voicemail, which isn't the default setting.

Businesses are also advised to disable the outbound call forward feature of the voicemail system over weekends, which is when the scam tends to take place.
