Washington ( CNN ) -- Supreme Court Justice Stephen Breyer was robbed last week by an intruder armed with a machete while Breyer was vacationing on the Caribbean island of Nevis , court officials said Monday . Breyer , his wife and two other guests were in the justice 's vacation home at the time , but officials said no one was hurt in the incident . The male assailant took $ 1,000 in cash and fled the scene , according to court spokeswoman Kathy Arberg . The robbery was reported to local authorities shortly after it happened last Thursday night , and local media said no arrests had been made as of Monday . A law enforcement official said the evidence so far indicates the incident was `` a crime of opportunity , '' and that police have seen nothing so far to indicate Breyer was targeted for robbery . The U.S . Marshals Service provides protection for members of the high court when they are traveling , and agency spokesman Jeff Carter said Monday that the marshals service `` is aware of the incident involving Justice Breyer on the Caribbean island of Nevis and is assisting the Supreme Court Police and local law enforcement authorities with the investigation as needed . '' He did not elaborate . FBI spokesman Paul Bresson said , `` We are assisting the local police with their investigation . '' Meanwhile , police on the island were `` actively searching for a known person of interest , '' Commissioner C.G . Walwyn of the Royal St. Christopher and Nevis Police Force said Monday . `` Our American-trained crime scene investigators and the members of our Criminal Investigators ( unit ) are working closely with the FBI on this case , '' he added . Breyer had no comment on the matter , and the court would not say if he had returned to the United States . The high court is in recess this week , but the justices have scheduled a closed-door meeting Friday to go over pending court business , and they resume public sessions next week . Nevis is part of the West Indies chain known as the Leeward Islands , located about 350 miles southeast of Puerto Rico . The court does not talk publicly about specific security arrangements for the justices , either when they are at home or on their frequent travels . Justice Ruth Bader Ginsburg traveled to Egypt and Tunisia last month as part of an outreach program sponsored by the State Department , which provided her security in the volatile region . Attacks on members of the federal judiciary are not new . Then-Justice David Souter was assaulted by a group of young males in 2004 while jogging alone in the evening near his Washington home . Souter suffered some minor bruises and was briefly treated then released from a local hospital . Justice Byron White was attacked in July 1982 while giving a speech in Utah . That incident led to regular protection by U.S. marshals for members of the court when they travel . The 73-year-old Breyer was nominated to the high court in 1994 , and is known as one of the most active and engaging members of the court . His wife is Dr. Joanna Breyer , a renowned pediatric psychologist . CNN 's Nigel Walwyn and Carol Cratty contributed to this report .
