Police narrow in on ex-convict who posed as student

Police have executed some search warrants in an effort to track down an ex-convict who impersonated a medical student at Wellington Hospital.

Peta Edward, 26, was seen disguised as a medical student on hospital grounds, on Tuesday.

The hospital and other government agencies since have put out alerts to keep an eye out for Edwards, police spokesman Nick Bohm said.

"He's not at his bail address so he is in breach of his bail conditions."

Police were urging Edwards to hand himself into police.

His benefit had also been stopped, Mr Bohm said.

Edwards was recognised on the hospital grounds by a Corrections officer, who spoke with him.

The officer said Edwards was dressed in a white lab coat with a stethoscope around his neck, Mr Bohm said.

"He's had a bit of a chat to him and he's [Edwards] said he was studying or doing something like that.

"He [the officer] thought that was pretty unusual and was aware of his recent release from prison and the release conditions that he had."

The officer then alerted police to Edwards' presence, Mr Bohm said.
