The bodies of two men have been found on a road, police said today.
West Yorkshire Police said they were discovered by a passing motorist in New Lane near its junction with Raikes Lane in Bradford at about 10.20pm yesterday.
A force spokesman said an inquiry is under way and a forensic examination of the scene is being carried out.
New Lane has been closed between Holme Lane and Tong Lane, the spokesman added.
This morning, police cordons were in place at either end of New Lane - each more than 200m from the scene.
At the junction of New Lane and the A58 Tong Lane, a police van and a police car guarded the entrance but there was little sign of activity and the scene was not visible.
The area where the bodies were found is open countryside - green meadows with pockets of woodland - just a mile or two from the suburbs of south Bradford.
Locals speculated that the bodies may have been dumped.
Alice Avery said: “It’s a quiet area. So you just don’t know what goes on at night time round here, do you?”
Police said a murder investigation had been launched.
Detective Superintendent Dick Nuttall said officers were trying to establish the identities of the men and the circumstances leading to their discovery.
He said: “We are also examining the possibility that these bodies were left on New Lane following an attack.
“I am particularly interested in hearing from anyone who was in the area of New Lane or Raikes Lane at the time or saw anything suspicious to come forward immediately.
“This is a rural and quiet area of Bradford and people may have noticed any unusual activity, especially at this time of night.
“At this stage we have not recovered any weapons; however, forensic officers are currently examining the scene.”
The detective said officers from the local Neighbourhood Policing Team would be patrolling the area to offer reassurance and speak to residents about any concerns.
Any witnesses or anyone with any information is asked to contact the Incident Room on (01924) 334693.
