During 2002 on which island were 8 british tourists rescued from armed
bandits by spear wielding locacls ?

Hi pjmulberry-ga,

Thanks for your question.

The island in question is Madagascar. A group of backpackers were
staying in Isalo National Park when bandits attacked their camp.
Locals armed with spears thwarted the robbers by rushing the camp en
masse.

Klare England of Nottingham was the tourist who received the most
press attention. An article in "the Daily Mail" identified her
companions as "seven other Britons."
