M61 Bolton: £10K reward offered for Constance Marten information

On January 5, the couple and the baby were on the M61 when their car broke down and caught fire near junction four at Farnworth.

The family are said to have left the vehicle and the motorway safely after breaking down, then walked to the Anchor Lane bridge which links the Highfield and Little Hulton areas.

The couple and their baby were last seen in Newhaven, East Sussex, on January 9, the Metropolitan Police said, but they believe the family are still in the UK.

They are believed to have been sleeping rough after buying camping equipment from a branch of Argos in east London on January 7.

Ms Marten, 35, and her partner Mark Gordon, 48, have lived an isolated life since they met in 2016.

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.
