Associate Justice Stephen Breyer of the United States Supreme Court was robbed by a man armed with a machete while vacationing on the island of Nevis in the West Indies last Thursday,  The Associated Press reported on Monday, quoting a spokeswoman for the Supreme Court.

Justice Breyer was in his vacation home with his wife, Joanna, and guests when the robber entered the home around 9 p.m. on Thursday. The assailant took approximately $1,000 in cash and fled, the spokeswoman said. No injuries were reported.

The robbery was reported to local officials on Thursday night.

The St. Kitts Nevis Observer, a local newspaper on the island, reported on Saturday that an F.B.I. agent had arrived on the island for an investigation. Supreme Court officials would not confirm to reporters who is leading the search.

It is not clear if Justice Breyer has returned to the United States. The justices will next meet in public on Feb. 21.
