A prisoner jumped from a police vehicle as it slowed down on a motorway after pretending to be ill.
Downie is not thought to be a danger to the public
Kevin Downie, 28, who had served three and a half years of an eight-year jail sentence for possession of a firearm, had been out on temporary licence.
He was returning to HMP Grendon in Aylesbury, Buckinghamshire, when he told prison officers he felt unwell and asked them to pull over.
As it slowed on the M60 near Chadderton, he jumped out and ran off.
Police said he had pretended to be sick out of the window of the silver people carrier they were travelling in.
'Not a risk'
When the car pulled onto the hard shoulder, Downie ran along the slip road and headed in the general direction of Broadway in Oldham.
He had been out of prison as part of a resettlement scheme.
Downie, who is from the Manchester area, is described as white and clean-shaven, with short blond hair.
He was wearing a black long-sleeved Reebok sweatshirt and grey Adidas trousers.
Greater Manchester Police have said he is not considered a risk to the public.
Detectives are advising members of the public not to approach him but to contact police immediately.
