Family members of a Russian man charged with hacking in the United States insist he is innocent and fear incarceration will kill him.

Roman Seleznev, son of a prominent Russian lawmaker, was arrested on bank fraud and other charges earlier this week. U.S. authorities allege that he hacked into computers at hundreds of retail businesses.

Seleznev's father, Valery, told a televised news conference on Friday that his son, who was left disabled after a 2010 bombing in Marrakesh, will die without his medication.

Seleznev Jr.'s girlfriend, Anna Otisko, said she was with him when he was arrested at the airport in the Maldives.

The Russian foreign ministry has accused Washington of kidnapping the man. U.S. officials have declined to say how or where he was apprehended.
