Police are continuing to search for the missing baby of Constance Marten as officers said they now have to "consider the possibility" that the infant has "come to harm".
The missing aristocrat, 35 and her partner Mark Gordon, 48 were taken into police custody on Monday after being found in Brighton. Officers are now scouring a large area between Brighton and Newhaven to find the pair's missing baby, who has not had any medical attention since birth in early January.
Speaking on Tuesday afternoon, Met Police Detective Superintendent Lewis Basford said that extensive searches are continuing for the baby through the use of police helicopters, drones, sniffer dogs and thermal imaging cameras. Det Supt Basford said: "Throughout this investigation our key priority has been finding the baby, and we remain committed to that."
