Police in Christchurch are looking for a prisoner on the run.
[image:1092:third:right]William Steven Cooper, 19, escaped from police custody on Monday and is thought to have impersonated another prisoner to do so.
Cooper was appearing in Christchurch District Court on robbery and firearms-related charges. He is considered dangerous and should not be approached.
Police believe Cooper may have made his way to Invercargill where he has connections.
Cooper is described as Maori, is 187 centimetres tall, with short dark hair.
He was last seen wearing a dark-coloured checked shirt, trackpants and black shoes with a large white Nike tick on the side.
