Constance Marten: Police custody for couple extended amid fears baby has come to 'serious harm'

Detective Superintendent Lewis Basford from the Metropolitan Police has given an update on the search for Constance Marten and Mark Gordon’s baby, saying officers “must consider that the baby has come to serious harm”.

The couple remain in custody and investigators have applied for a 36-hour extension to hold them for further questioning.

Mr Basford told reporters in Brighton: “This is a hugely difficult and painstaking search operation, covering a vast area of some 90 square miles.

“We’re using every resource we have at our disposal to find the baby.”

He urged the public to remain vigilant and continue providing information to the investigation team.

Some 200 police officers are continuing an urgent search for the baby of Constance Marten and her partner Mark Gordon.

The runaway pair were discovered in Brighton on Monday then arrested on suspicion of child neglect and suspicion of gross negligence manslaughter.

Officers are scouring an area of 90 square miles including allotments and woodland, stretching from Brighton to the place they were last seen.

A member of the public, who had seen media reports about the couple, phoned 999 after seeing them withdraw money from a cashpoint shortly before 9.30pm. However, their baby was not found with them.

Detective Superintendent Lewis Basford said police still hoped to find the child safe and well, with a helicopter, sniffer dogs, thermal imaging cameras and drones being used in the search.

He said officers had received no information about the welfare or location of the child since the pair were detained.

Mr Basford said: “We have had a significant period of time in a custody facility with both Constance and Mark.

“At this time we have not furthered that information, which has now obviously led to the position where we feel that the risk is getting so great that we now have to consider the possibility that the baby has come to harm."
