The family of 21-year-old Amelia Bambridge who went missing after a beach party in Cambodia have flown out to join a growing search operation for the backpacker.

Ms Bambridge, from Worthing, West Sussex, was last seen by friends at around 3am on Thursday morning at a beach party on the island of Koh Rong.

Police, scuba divers, government officials and volunteers have joined the search, and on Sunday were also using a drone to scour the dense jungle and coastline.
