An elderly woman and her daughter are shaken after a group of four pulled them from their car in New Plymouth, before a pursuit which damaged four police cars.
A 15, 17, 18 and 20-year-old pulled the 72-year-old and her 48-year-old daughter from their vehicle, before making off with it at 8pm on Friday night.
Police were called around to the intersection of Rainsford St and St Aubyn St, where a chase began.
The car was slowed by road spikes around 40km later, the chase finally ending at Rahotu, north of Opunake. Four police cars were damaged.
The elderly woman and her daughter were hospitalised with cuts and abrasions, and later discharged.
"We are continuing to provide support to the two victims, who were very shaken by what happened," said Det Const Anthony Temple says.
The offenders appeared in court this morning.
Investigations into the incident continue and police are asking for any witnesses with information to call New Plymouth police on (06) 759 5500.
