A 25-year-old man was stabbed to death in the street as ghoulish onlookers blocked residents from helping the dying man as they filmed him on their phones.
The victim, who has not been named, was knifed in Erdington, Birmingham, on Monday (29/11) afternoon.
Police and paramedics scrambled to Chudleigh Road at around 4.15pm but despite rushing the man to hospital he died a short time later.
An 18-year-old man was arrested in the Erdington area on suspicion of murder.
Witnesses told of their "utter disgust" after ghoulish onlookers filmed the man bleeding to death as he lay on the ground.
One resident said: "There was what looked like a fight but when the man went down he was surrounded by people pointing their phones at him.
"It was obvious he was badly hurt but no one did anything to help him.
"My neighbour desperately tried to help him but couldn't get through the crowd.
"It is utterly disgusting behaviour, where is people's decency?"
A cordon remains in place near the junction of Reservoir Road while officers conduct a fingertip search of the murder scene.
Detective Inspector Wes Martin, of West Midlands Police, said: "A young man has tragically lost his life and we're doing all we can to support his family at this awful time.
"We've made some quick progress by arresting a suspect on suspicion of murder.
"However, we remain keen to hear from anyone who may have information. Anyone who may be able to help us needs to contact us.
"We're reviewing all CCTV possibilities and we're asking people in the area to check any dashcam or doorbell footage which can help us fully establish what has happened during this terrible incident."
