A man arrested on suspicion of causing death by dangerous driving following the death of a brother and sister in Cheetham Hill has been rebailed.
At about 10.15pm on Saturday 1 September 2012, police were called to Bury New Road at its junction with Sherborne Street following reports a silver Mercedes and a red Nissan Micra had collided.
Officers attended and the driver of the Micra, a 32-year-old man, and the front seat passenger, a 37-year-old woman, were pronounced dead at the scene.
They were later identified as Kulwant Singh, of Salford, and his sister Ravel Kaur of Cheetham Hill.
In the back of the Micra were Ravel Kaur's two sons, who are 16 and 17-years-old. Both are now making a good recovery.
The driver of the Mercedes, an 18-year-old man, was arrested on suspicion of causing death by dangerous driving and has been rebailed until 24 January 2013. A file has been prepared and sent to the Crown Prosecution Service to make a final decision.
A second man, aged 19 who was driving a grey Volkswagen Golf, will face no further action and has been released from bail without charge.
Police are now satisfied the two vehicles were not racing at the time of the collision.
Police Sergeant Danny Byrne, from the Serious Collision Investigation Unit, said: "This is an incredibly complex and sensitive investigation and it is important we balance the needs of the families, who have suffered unimaginable grief, with the facts as we have them.
"Having reviewed all the available information and evidence, I am satisfied that the vehicles were not racing each other and the driver of the VW Golf, who has been released without any further action, is not involved in this incident.
"A file of evidence has now been completed and passed to the Crown Prosecution Service for a decision on the driver of the Mercedes, who has been bailed until 24 January 2013 while the CPS assess the case.
"I know there is a lot of speculation and media interest in this incident, so when any decision is made we will let everyone know, but I stress that our primary focus is to ensure this incident is investigated thoroughly and to protect the families of Kulwant and Ravel."
