New images of a missing couple and their newborn baby have been released by the Metropolitan Police which has offered a £10,000 reward for information.

Detectives say they are “extremely concerned” about Mark Gordon, 48, and Constance Marten, 35, who went missing after their car broke down in Bolton on 5 January.

Police say their baby has been exposed to sub-zero temperatures for almost a month and the couple were “constantly moving and awake for at least a few days” after the birth.

The new pictures show the couple on the move on the evening of Saturday 8 January.

The images show them walking near Brick Lane, east London at around 11.45pm where they dumped a pushchair.

They then get a taxi to Haringey, north London where they got into a second taxi just before 1.30am on Sunday morning.

The couple were then dropped off outside the port in Newhaven, East Sussex just before 5am on Sunday morning, which was captured in a CCTV image.

They were carrying bags containing a two-man tent, sleeping bags and pillows that they had purchased from Argos the evening before.

The couple then walked to where the A259 crosses over the B2109 and were last seen sheltering from the rain under the overpass at around 6am. It is the last known sighting of the pair.

Police say the couple could still be camping somewhere in the UK.

Ms Marten, 35, who is from a wealthy family with connections to the royals, has lived an isolated life with Mr Gordon, a 48-year-old convicted sex offender, since they met in 2016.

The couple went missing after their car caught fire near Bolton on Thursday 5 January. It is thought most of their belongings were destroyed in the fire.

Police believe Ms Marten may have given birth just one or two days before the fire. Neither her nor their newborn have had any medical attention since they went missing.

Detective Superintendent Lewis Basford, who is leading the investigation, said: “We continue to be extremely concerned about the health and wellbeing of the newborn baby, which has had no medical care and has been on the move, and possibly exposed to sub-zero temperatures, for almost a month now.

“We’re also concerned for the welfare of Constance and Mark because our enquiries suggest that they were constantly moving and awake for at least a few days – which must be especially draining on someone who had recently given birth with no medical attention.

“Finding the baby is our top priority and we are now offering a £10,000 reward to anyone who provides information which leads to them being found.”
