Two men have been arrested on suspicion of murder after a Congolese mother-of-nine and her nephew were shot dead at a home in north London last week. Annie Besala Ekofo, 53, and Bervil Kalikaka-Ekofo, 21, were killed after bullets rang out in Elmhurst Crescent, East Finchley.
A 20-year-old man was arrested in the early hours of Saturday, 17 September and has subsequently been released on bail to a date in late October.
A second man, 24, was arrested on Sunday (18 September) is currently in custody at a north London police station.
Four other people, including a child, who were also inside the address at the time were not harmed.
Police earlier said there is no evidence to suggest the victims were the intended targets of the shooting, adding that one line of enquiry will explore if there is any evidence to suggest that anyone else associated with the address was.
Family members broke down in tears upon learning Annie and Bervil had been killed. One of Annie's son's said: "Don't say my mum is dead," after being told of her fate. "My mum is dead?" he continued before shouting "No!"
Detective Chief Inspector Andrew Partridge from the Met's Homicide and Major Crime Command said: "Specially trained detectives have been deployed to the family and are providing support to them at this undoubtedly difficult time. Understandably, they are devastated by the loss of not one, but two members of their family.
"The investigation continues at a fast pace and we have already spoken to a number of people who have come forward and provided useful information to the investigation. I would like to thank those witnesses, and reiterate my previous appeal for anyone who is yet to speak to us to do so as soon as possible.
"Whilst the murders took place early in the morning, I am confident that there would have been people up and about, getting ready for work and school. It is possible that someone may have noticed a stranger on the estate, or a vehicle that is not usually there. It may have seemed unimportant at the time, but could be vital in leading us to the person or persons who committed these brutal murders."
