Detectives investigating the murder of a man in Islington on New Year's Day have named him.
Police were called by the London Ambulance Service (LAS) on New Years Day, Monday, 1 January at around 02:35 hours to a flat in Bartholomew Court, EC1.
Officers attended along with the LAS and found two men - both aged 20 - suffering from stab injuries.
Steve Frank Narvaez-Jara, 20 from south-London who has been formally identified was pronounced dead at the scene at 03:26 hours.
A post mortem examination took place on Wednesday, 3 January at Whittington Hospital and a preliminary cause of death was given as incised wounds to his chest.
A second 20-year-old victim, also stabbed during the incident, was taken to a north London hospital where he remains in a critical but stable condition.
Three men arrested on suspicion of murder, two aged 19 [A] and [C] and one aged 18 [B] have all been bailed to a date in late January.
Detectives from the Met's Homicide and Major Crime Command investigate, led by DCI Andrew Packer.
Enquiries are ongoing.
DCI Packer said: "I am appealing to anyone who attended the party to come forward and speak to police, I need to trace everyone who was present as they may be witnesses to this violent attack."
The family of Steve Frank Narvaez-Jara said: "Someone has taken away our only beautiful son and brother without thinking about the pain and sadness that it has caused our family and friends, especially his two-year-old sister and two older sisters aged 15 and 16, they all loved him unconditionally. We pray to God that Steve's death brings knife crime to and end."
