A suspected drug driver was caught after blocking the way of a police car pursuing another vehicle.
Officers came across a vehicle driving in the dark without any lights in Bolton Road, Atherton, overnight.
As police tried to pull it over, another vehicle - a silver Mercedes - failed to stop at the side of the road and blocked the way of police.
When the Mercedes was then followed, it turned on to a cul-de-sac where one of the passengers fled.
A roadside breath test saw the driver of the vehicle test positive for cannabis and cocaine.
A 20-year-old man was arrested on suspicion of driving under the influence of drugs, possession of a bladed article, failing to stop and possession of drugs.
He remains in custody to be quizzed by police.
In a post on the GMP Leigh, Atherton and Hindley Facebook page, officers said: "Officers from the #TransportUnit attempted to stop a vehicle last night on Bolton Road driving without lights on in the dark.
