St. Lucia police say they have arrested a man who killed a P.E.I. senior who was visiting the island last week.

Colin Peter, 75, was walking along the beach with his wife Gwen last Thursday afternoon when he was attacked, St. Lucia police spokeswoman Aniel Innocent said Wednesday.

The Guernsey Cove was taken to hospital where he later died. His wife was not injured.

Clinton Reynolds of St Lucia's news channel DBS TV told CBC that Peter's attacker did not resist arrest, confessed to the crime and that he is expected to be formally charged with the murder early this week.
DBS TV had reported Peter and Gwen were on the island tracing his family roots and staying at a private residence.

The Peter's three children flew to St. Lucia Saturday to join their mother and attend a private funeral.
