Traffic police investigating an accident in which three people died have launched a fresh appeal to trace a car seen near the crash scene.
Inquiries into the tragedy in Birmingham have revealed that a silver Subaru Impreza estate was driving "very fast and very close" to a Rover 216 which collided with a concrete pillar, killing three of the four occupants.
The Subaru left the scene after the incident near the city's Hurricane Park industrial estate at approximately 10pm on February 18 this year.
Inspector Ian Iliffe, who is leading the investigation, revealed that two anonymous telephone calls had been received - one at Birmingham's Queens Road police station and one to Crimestoppers - in which valuable information about the Subaru driver had been provided.
Insp Iliffe explained: "The information that these callers have provided is very important to the investigation and I would urge them to come forward and speak to officers.
"I am very interested in what they have got to say and I would really like to be able to ask them more questions.
"The driver of the Subaru must have a conscience, and I appeal for that person to come forward.
"I would like the driver of the Subaru to think about what happened on the night of February 18, where three people died. It must be playing on their mind."
Insp Iliffe added: "There is a possibility that other people were in the Subaru, they must be thinking about what happened.
"I have no doubt it was a frightening event for them. If they turned around and saw the devastation behind them it will be engraved in their memories forever. Please come forward and put an end to the silence."
Anyone with information should call the road policing unit at Queens Road police station on 0121 322 6235.
