Detectives investigating a fatal shooting have made a new arrest and continue to appeal for the publics’ help.

An 18-year-old man was arrested on Friday at an address in north London on suspicion of murder.

The arrest follows the death of Richard Odunze-Dim, 20, who was gunned down at an address in St Joseph's Road on December 18.

Three men arrested at the scene have since been released with no further action.

Two other men arrested on December 23, have been bailed to a date in mid-January.

Police were initially called by the London Ambulance Service at around 9:15pm on December 18 to reports of a man suffering a gunshot wound in St Joseph's Road.

Armed officers responded along with other emergency services, but Richard Odunze-Dim was pronounced dead at the scene at 10:10pm.

A post-mortem on December 21 found the cause of death to be a gunshot wound.

Detective Chief Inspector Gary Holmes, who is leading the investigation, said: “Whilst we have made a new arrest, we still want to hear from any witnesses who may have been in the area at the time, or have heard anything about it since.

“We understand that witnesses may be frightened to contact us, but rest assured, we will treat all information in a sensitive manner. I urge anyone who witnessed anything suspicious or persons with information to come forward so that I can give justice to Richard and his family, whose lives have been ruined by this tragic and brutal murder.

“Any information, no matter how insignificant, could really help take a murderer off the streets and may help save more lives.”

A spokesman for Richard's family added: "Whoever is protecting these individuals, or knows anything about this at all, must come forward. Too many families have gone through the pain that we are going through now.

"We do not want vengeance - we just want the violence to end."

Anyone with information is asked to contact the dedicated HMCC incident room on 020 8345 1570 or call police on 101, quoting the reference CAD 7822/18Dec.
