A teenager has been charged with the murder of a young man in Crawley.
The victim has now been formally identified as 24-year-old Arnold Potter, from Maidenbower.
Post mortem results returned on Saturday confirmed he died from being stabbed to the torso.
The incident occurred in Watson Close around 6.40pm on Thursday , and despite the best efforts of members of the public and emergency services who attempted CPR, Arnold was sadly pronounced dead at the scene.
A 17-year-old boy from Crawley handed himself into police on Friday and was arrested on suspicion of murder.
He has now been charged with murder, possession of an offensive weapon in a public place (a knife) and possession with intent to supply a Class A drug (cocaine).
He has been remanded in custody ahead of a hearing at Brighton Magistrates' Court on Monday. Due to his age he cannot be identified for legal reasons.
Three people arrested in connection with the incident have been released but remain under investigation pending further enquiries.
A further four people have since been released without charge and will face no further action.
Detective Chief Inspector Andy Richardson said: "This was a tragic incident which has had a devastating effect on the community, and in particular on the friends and family of the victim. Our thoughts are with them at this difficult time.
