CHARLOTTE, NORTH CAROLINA (EmergencyNet News) - A tense standoff at a Charlotte courthouse with a man police believe carried a small bomb came to an end on Thursday afternoon. The five-hour standoff began when the man was stopped at a security checkpoint after guards became suspicious about a package he had brought into the courthouse.

The man came to the courthouse for a child custody hearing and was stopped at about 1000 EST after passing through a metal detector and putting what one witness described as a black bag through an X-ray machine. When guards asked to examine the bag, he held up a device with a switch on it and indicated the package in the scanner was a bomb.

During the standoff, the man calmly stood near the metal detector in the courthouse lobby holding a small detonator while the package remained undisturbed inside the X-ray machine. He reportedly asked to talk to a judge and an FBI agent. He surrendered at about 1500 EST.
