Barnet stabbings: Man arrested after mother and young daughter found dead

"The deceased are believed to be mother and daughter," the Met said in a statement. "An investigation has been launched led by detectives from the Met’s Specialist Crime Command and a 37-year-old man has been arrested on suspicion of murder. "The deceased and the arrested man were known to each other." Chief Superintendent Sara Leach, policing commander for the North West including Barnet, said: “The whole community will be shocked and saddened to hear of this terrible incident. “Our thoughts are with the family and friends of the woman and child who have died and also with the officers and paramedics who were first to arrive at what was an incredibly challenging scene." Leach said specialist detectives are working to establish what took place. "While they are keeping an open mind as to what has taken place, I would like to reassure residents in the local area that there is nothing to indicate, at this stage, that anyone else was involved in this incident." Leach urged anyone who "saw or heard anything unusual earlier today, or in recent days" to contact police as "your information could be vital as the investigation moves forward”. Information can be provided to police by calling 101 with the reference 3590/21JUN. Alternatively, it can be provided to the independent charity Crimestoppers, anonymously, on 0800 555 111.
