Adam Glanville and his 43-year-old mother Karima Mahmoud are thought to be together. They have not been seen since Monday, June 3, when they were last in Richmond.
The Metropolitan Police, who launched a social media appeal in July, stated on its website that it is attempting to identify both of them. Ms. Mahmoud is in violation of a family court order.
The investigation’s chief detective, detective sergeant Mary Dawson, stated that after exhausting “all lines of inquiry to locate the pair,” authorities are once more requesting assistance from the public.
Ms Dawson said there is no reason to assume any of them has come to any harm, but as time passes they are “increasingly concerned for their welfare”.
Karima might have changed how she looked, the force added.
