A 16-year-old boy has been charged with the murder of a father-of-four who was stabbed to death.
James Gibbons died soon after he was attacked in the street where he lived in Laindon, Essex, on Sunday evening – the day of his twin daughters’ birthday.
Essex Police said the 34-year-old self-employed plumber is believed to have gone to the aid of another man, then died in an altercation that ensued.
Six teenagers were arrested as part of the force’s investigation.
A 16-year-old boy has now been charged with murder and will appear at Chelmsford Magistrates’ Court on Friday.
A 13-year-old boy arrested on suspicion of murder has been released on bail until 14 May.
Police said two girls, aged 15 and 16, who were arrested on suspicion of murder, have been told they face no further charges.
Meanwhile, a 14-year-old boy arrested in connection with the murder has been released on bail until 25 May.
A 13-year-old boy has been told he faces no further action in relation to the murder, but has been released on bail in connection with an assault offence, police said.
Mr Gibbons, of Iris Mews, was described by his family as an "amazing father of four young children, engaged to his partner of 11 years, and… a loving and supportive son and brother".
In a statement released through police, they said: "James was a hard-working family-orientated man, who ran his own bathroom-fitting company and was looking forward to a positive future for him and his family.
"This tragedy occurred after he had spent the day celebrating his two-year-old twin girls’ birthday at home and we are absolutely broken beyond belief at this pointless loss which has had a devastating effect on us all.
"James was the kind of person who would always be prepared to help anyone less fortunate than himself, which is what he was doing on Sunday night.
"As a family, we are urging anyone to come forward with any information that may help the police as they investigate James’ death in the hope we can get justice."
