Officers of the police force’s Cyber Crime Unit said yesterday that they had detained a 31-year-old man on charges of possessing and trading in child pornography following months of investigation. The suspect is said to have eluded authorities by illegally accessing the IP addresses of other web users. After eventually tracing his Attica home, police officers raided the premises on Friday and confiscated thousands of digital photographs and videos of children being sexually abused. The suspect had been on vacation outside Attica at the time of the raid but was traced and arrested, police said. He was to face an Athens prosecutor yesterday.
