The search for missing backpacker Amelia Bambridge

The sister of a British backpacker missing in Cambodia has said the 21-year-old was having “the best time ever” just hours before she went missing.

Amelia Bambridge was last seen at a party on Police Beach on Koh Rong island at 3am on 24 October.

The 21-year-old was travelling on her own for the first time.

Sky’s south east Asia correspondent Siobhan Robbins reports from Koh Rong.
