Police are treating the death of a woman killed in a car crash as manslaughter after they discovered the collision was caused by the deliberate puncture of one of her tyres.
Joanna Smith, who was 32 and lived in Northampton, died when her Honda Jazz was involved in a collision on the A45 near Earls Barton in April.
She was originally from Poland.
Forensic investigations have shown that one of the tyres on the car had been deliberately tampered with before she began her journey.
Following the collision, officers were told that a further three vehicles parked close to Joanna’s also had tyres damaged.
Joanna’s car was parked in a communal car park near Budgens at Grange Park when it was damaged.
It is believed that the tyre had only partially deflated and that she did not realise it was punctured when she started her journey to work.
