Two houses were damaged in an arson attack at Magherafelt last night.
The fire in a garden at Piney Hill destroyed an oil tank, fencing and bins shortly after 10pm.
A woman resident in her 50s was not injured in the incident.

Or if someone would prefer to provide information without giving their details, they can contact the independent charity Criemstoppers and speak to them anonymously on 0800 555 111.”
