Christchurch Police hunting stolen car after Blenheim Road crash this morning

Police began pursuing the stolen vehicle around 5:50am, before it pulled over near the corner of Blenheim and Wharenui Road.

However, as officers approached the car, the driver fled again - and as police pulled back onto the road to give chase again, they crashed with another vehicle.

No one was injured ... but westbound traffic was detoured for more than an hour.

Police say they will investigate the crash and pursuit internally - something that's standard practise.
