An 18-year-old has been arrested and accused of hacking into websites of the U.S. government and the international crime fighting agency Interpol, says an MSNBC report.

In a raid on the suspect's house in greater Athens on Monday, says the report, police seized computers, flares, shotgun cartridges, a homemade incendiary device, 130 fake credit cards, and $11,500 and $300 in cash hidden in a hollowed-out book.

The suspect, who was not further identified, was arrested there on charges of computer fraud, forgery, illegal violation of privacy, and illegal weapons possession, the report says.

Police cybercrime and anti-terrorism divisions are involved in the investigation, says the report, which also will examine possible links between the suspect and local militant groups that have carried out bombings in the past, mostly targeting Greek banks and government agencies.

The alleged cyber attacks occurred in 2008 and 2009 against the U.S. and Interpol sites, with the suspect using botnets: networks of computers carrying malicious software unknown to the users.

The police statement did not identify the computer sites that were allegedly hacked into, the report says.
