Teenager arrested after sending threat over Xbox Live

According to media reports, a Maryland teen, who has not been identified by name, stole the login credentials of an Xbox Live user from New Jersey and began sending messages to various students at his school, allegedly writing that he intended to bring a gun the next day and open fire.

Concerned parents called the police, who tracked down the originating Xbox Live account. The account holder was met by authorities, but convinced them he wasn't the one who sent the message. From there, police contacted Microsoft to track down the login history of the account in question, and were able to locate the actual suspect in Maryland.
