Double murderer still on the run in Vic

A violent double murderer who breached parole is still on the run a week after he disappeared.

John Wallace Lindrea has not been found and the investigation is ongoing, police say.

He was last seen in the Warrnambool area on Good Friday, a day after his parole was cancelled and police say he is a threat to the community.

Detective Superintendent Peter De Santo on Tuesday said he could not reveal why Lindrea's parole had been revoked, but did say his tracking device was no longer working.

"We believe the ankle bracelet has been cut," he said.

Lindrea and his partner Sally Roach, 46, may be travelling in a white 2011 Hyundai iX35 wagon with registration YTK 659.
