Three people have been charged with the murder of a teenager who was stabbed in a house in Preston on December 23.
Sarmad Al-Saidi, 16, was found with "critical" injuries to his chest and legs at an address in Chatham Place on Wednesday evening before passing away in hospital yesterday.
18-year-old Jamie Dixon from Leyland appeared before Preston Magistrates charged with Sarmad's murder this morning.
Two other teenagers, aged 16 and 17, have also been charged with murder - they cannot be named for legal reasons.
Two people arrested on suspicion of assisting an offender have been released under investigation, according to Lancashire Police.
DCI Lee Wilson, of the Force Major Investigation Team, said: "This incident has resulted in a young man losing his life and my thoughts are very much with Sarmad’s family and friends at this incredibly difficult time.
"Sarmad’s family have been supported by specially-trained officers throughout this investigation and that will continue.
"While we have now charged a man and two teenagers with Sarmad’s murder, our investigation is very much ongoing and I would ask anybody with information that could assist us to come forward.
"I know this incident has had a major impact on the community and I would like to thank the public for their extremely valuable support with this murder inquiry."
