Chagossians away from home were deliberately marooned by travel bans after 1967.

Evidence

Once British officials had agreed and base construction appeared imminent, any Chagossians who left Chagos after 1967 for medical treatment or a routine vacation in Mauritius were barred from returning home. Agents for the steamship company that connected the islands told the travelers that their islands had been sold and that they could never return. The Chagossians were marooned in Mauritius, separated from many of their family members and almost all their possessions. — David Vine, Base Nation_ How U.S. Military Bases…, 180
