The newborn which went missing with parents Constance Marten and Mark Gordon may have been dead for some time as police said they have been unable to tell the baby s gender
Napier Marten said it is very alarming after his daughter, 35, was arrested with Mark Gordon, 48, in Brighton last night but refused to say where the newborn is.
The couple were heard having a row as they walked along Stanmer Villas at just before 9.30pm last night, five minutes before they were held, exclusive footage obtained by MailOnline shows.
Constance Marten (pictured) and Mark Gordon, along with their recently born child, are missing after their vehicle broke down near junction four of the M61, near Bolton, on Thursday night.
