Det Supt Lewis Basford is head of Public Protection - East BCU in the Met. One of their areas of speciality is child protection/neglect/abuse and missing persons. Not sure why they've taken over from Sussex though.
EDIT: Based on his Twitter he shared an appeal before they were found so they might have already been involved. Perhaps they got involved when they were spotted in East Ham?
Oh dear God noThey found the remains of a baby
I honestly can't believe what I'm hearing I wholeheartedly thought that baby was going to be with someone.
