Rapper T.I. appeared in the Federal Courthouse in Atlanta for the first time today at 3:00 PM on weapons charges and has been ordered held without bail.

T.I., born Clifford Harris Jr., had his hands cuffed and his legs chained as he entered the packed courtroom.

His lawyers unsuccessfully sought bail for the rapper, which was denied by U.S. Magistrate Judge Alan Baverman.

ATF agents arrested the rapper in an Atlanta shopping center after he allegedly attempted to illegally purchase machine guns through a bodyguard who was working for the government.

A subsequent raid of his house turned up numerous assault rifles and loaded handguns.

T.I. will appear in court on Friday (October 19), where Judge Baverman will determine whether there was probable cause for the rapper's arrest and to decide if he will be eligible for bail before his trial.
