Federal authorities arrested a 17-year-old New Hampshire high school dropout Wednesday and charged him with hacking into a California Web site.

Dennis M. Moran, who calls himself "Coolio" on the Internet, was arrested at his parents_ home in Wolfeboro, New Hampshire, on felony charges for allegedly gaining unauthorized access to a DARE.com computer system in Los Angeles. Moran surrendered without incident and was charged as an adult with two counts of unauthorized access to a computer system. Each charge carries up to 15 years in prison. He was released on $5,000 bail, and no arraignment was set. Moran allegedly gained unauthorized access to the anti-drug Web site on two occasions last November, New Hampshire Attorney General Philip T. McLaughlin said.

The Los Angeles Police Department and the Los Angeles division of the FBI conducted the initial investigation. When they discovered that the computer intrusion at DARE had originated in New Hampshire, they referred the case to the FBI_s New England office and to New Hampshire authorities, an FBI press release said.
