Search for man in missing Alice Gross case

Police investigating the disappearance of the teenager Alice Gross have named a man they want to speak with in the hunt to find her.

The 14-year-old, from Hanwell, went missing almost three weeks ago after going for a walk along a canal in west London.

Detectives want to speak to 41-year-old Arnis Zalkalns. He was last seen at his Ealing home on 3 September - and has since been reported missing. Police say he is not a suspect.

BBC London reporter Alex Bushill spoke to Det Supt Carl Mehta.
