BOSTON -- A Massachusetts man rescued off the coast of Cuba by a Disney cruise ship was arrested Wednesday in connection with a computer attack on a Boston hospital two years ago.

Federal prosecutors allege that 31-year-old Martin Gottesfeld had a role in a 2014 computer attack at the Boston Children's Hospital in the name of the hacking group Anonymous.

He and his wife made a distress call Tuesday after their boat ran into trouble.

According to a release by prosecutors, police conducted a well-being check after receiving calls from his employer and relatives, saying they had not seen them in several weeks. Responding officers soon found that no one was home.

Prosecutors allege Gottesfeld fled as he had been aware of the investigation into the hospital hack. The FBI had previously reportedly searched his home in October 2014, they added.

Gottesfeld was arrested Wednesday on a conspiracy charge after the Disney ship returned to Miami.

Authorities say the hack in question was in protest of the hospital's treatment of a Connecticut teenager at the center of a custody dispute, referred to as "Patient A" in the complaint affidavit.

An affidavit, obtained by CBS Boston, also stated that Gottesefield had posted a YouTube video in March 2014, in the name of Anonymous, saying in a computer-generated voice that the group "will punish all those held accountable and will not relent until [Patient A] is free."

Authorities say the YouTube video directed viewers to a posting on another website -- pastebin.com --- that contained information about the hospital's server necessary to initiate an attack.

The hospital's network was then attacked on April 19, 2014, disrupting operations for nearly a week, according to the station. The hack led to a disruption of the hospital's daily activities, as well as the research being done at the hospital.

According to the affidavit, Gottesfeld was later interviewed in October 2014. He allegedly admitted to operating the YouTube account that posted the video and to posting the video. However, he reportedly denied any involvement in the hack attack.

An attorney for Gottesfeld declined to comment.
