Police have named a teenager whose death is being treated as murder as 18-year-old Jay Benton.
Mr Benton was found in cardiac arrest at a property in Frescade Crescent, Basingstoke, Hampshire, on Wednesday afternoon.
The victim, of Berkeley Drive, Basingstoke, was taken to North Hampshire Hospital where he was pronounced dead.
A 14-year-old girl and a 16-year-old boy from Basingstoke were released on bail last night until October 29, Hampshire Police said.
The force's major investigation team has launched an investigation into the teenager's death, codenamed Operation Plate.
Detective Inspector Ben Chivers, of Basingstoke CID, said: ''Our thoughts are with the family of Jay at this very difficult time.
''The investigation into the circumstances surrounding his death continues. We would urge members of the local community to remain calm and to continue to contact police with any information that may assist with our investigation.''
He said earlier: ''At this time, the cause of death remains unknown and therefore, while we continue to investigate the circumstances surrounding the incident, we are treating the death as suspicious.
''The man who died and the two people who were arrested were known to one another and there is no wider risk to members of the public.''
A South Central Ambulance Service spokesman said two ambulances attended the scene after receiving a report of a man with a possible head injury.
Friends have spoken of their shock after Mr Benton's death.

A post-mortem examination has been conducted by a Home Office pathologist but the cause of death is yet to be determined. Further forensic examinations will take place.
