(Update: 9:15 a.m. EDT, April 16) -- The Associated Press has reported that police in St. Lucia have arrested one of four suspects in last week's armed robbery of Celebrity Eclipse passengers.

According to the report, police said the arrested man would be charged and that he had confessed to the crime in a written statement. "When he was detained, the suspect had $105 in U.S. currency, which detectives believe was money stolen from the tourists," the police statement said.

Two other suspects have also been questioned, but the report said it was unclear if further arrests would be made.

(Updated, 1:00 p.m. EDT) Celebrity Cruises has confirmed that 55 passengers and two crewmembers from Celebrity Eclipse were robbed at gunpoint on Friday, April 12 while in St. Lucia. No one was injured during the robbery.

Passengers were visiting the Botanical Gardens in Soufriere at the time of the robbery and were on two Celebrity-sponsored shore excursions, "Breathtaking Soufriere and Warm Mineral Baths" and "Land and Sea to the Pitons," both of which were traveling on the same bus.

"The affected guests have been contacted by our Guest Care Team to offer assistance, if necessary," a Celebrity spokeswoman told Cruise Critic. "We are thankful that none of our guests were injured in this unfortunate event, and will continue to provide them any support they may need."

The incident was reported to the local police, who are investigating. The cruise line is "monitoring the safety situation in St. Lucia."

Cruise Critic was first alerted to the robbery by members onboard ship. Host Andy e-mailed us from the ship and Arizona Cruz Chic posted about it on the Cruise Critic forum.

"We are on the Eclipse," Arizona Cruz Chic wrote. "Yesterday we were ported in St. Lucia. One of the ship tours was robbed at gun point by 3 masked gunmen. We're not on the tour, but friends were. They said one woman fell and broke her leg; no one else was injured. All their money and jewelry were taken."

Host Andy also mentioned reports of a woman breaking her leg and said officers and crew on the ship had not mentioned the incident to passengers. There's "a lot of buzz" among the passengers, though, he added.

Celebrity Eclipse is in the middle of a 14-night Caribbean cruise. St. Lucia was the fourth port of call.
