A woman has been arrested for failing to provide a roadside breath test.
The incident happened on Friday night when members of Norfolk And Suffolk Roads and Armed Policing team stopped the driver as part of routine checks.
When the woman failed to provide a roadside breath test she was arrested and once in custody was found to be more than three times over the legal drink-drive limit.
