Murder detectives want to talk two men and a woman with a pushchair who could be vital witnesses to Delaney’s death.
Delaney Brown is thought to have been knocked off his bike by a silver BMW on Vincent Road, Luton, last Wednesday.
The damaged car had been stolen, and was found abandoned nearby.
Detectives believe a woman with a buggy and two men in Balfour Beatty uniforms were in the area at the time and may have seen what happened
Yesterday, a week after Delaney died in Vincent Road, Luton detectives and officers from the local policing team conducted anniversary checks in the area.
Residents and motorists were stopped in the street between 4pm and 5pm in a hope that they would be able to further the investigation in to Delaney’s death.
Posters and leaflets were circulated in the area and house to house enquiries were also conducted.
Detective Chief Inspector Steve Collin, who is leading the inquiry, said: “Yesterday’s operation was extremely useful and did allow us to gather information about a number of people who were seen in the area at the time Delaney was knocked from his bicycle.
“A woman pushing a buggy with two children was seen in Vincent Road moments before the collision. She has been described as white, with a tanned complexion, approximately 5’6” tall, in her late 20’s, with dark hair in a pony tail. It is believed she turned around and walked away in the opposite direction when the collision happened. Two men wearing Belfour Beatty uniforms were also seen in the street at around the same time.
Detectives are still continuing to appeal to the public for information about this crime and are also seeking information about the silver series one BMW (registration number WF11 RWV) which was found in Morris Close abandoned the following day with damage consistent with a collision.
