The grandparents of a toddler who died in the French Alps have been arrested on suspicion of murder.

Philippe and Anne Vedovini, both 59, were arrested on Tuesday along with two of their adult children.

All four are facing charges of “intentional homicide” and “concealing a corpse”, according to a statement from Aix-en-Provence prosecutors.

Marie and Colomban Soleil, the boy’s parents, are not believed to be the two adult children arrested.

Police searched the grandparents’ home on Tuesday morning and removed a van from the premises, according to French media.
