Detectives are making a new appeal for information on the first anniversary of the death of a woman from Northampton who was killed in a car crash after her tyres were vandalised.
Joanna Smith, who was 32, died on the A45 in Earls Barton a year ago. A manslaughter investigation was launched after it was discovered that one of her rear tyres had been deliberately punctured.
The incident was linked to a spate of tyre vandalism in the area. Seven people were arrested and released without charge.
