BASSETERRE, St. Kitts — A police spokesman in the Caribbean nation of St. Kitts and Nevis says a “person of interest” is in custody in the robbery of U. S. Supreme Court Justice Stephen Breyer.

Sgt. Alonzo Carty said Monday that Vedel K. Browne turned himself into police late Saturday, and he has not been charged. Authorities can hold him for 72 hours before filing charges.

The 73-year-old Supreme Court justice, his wife and several guests were confronted by a machete-wielding robber inside their Nevis vacation home. Officials have said no one was hurt, but the robber took about $1,000.
