According to Channel 4 News, A Bomb Threat has the federal district court locked down with no one allowed to enter:
A bomb threat has the federal court building in downtown Detroit on lockdown Tuesday morning.
Detroit police said the threat was called in to the First Precinct.
A police K-9 unit is being brought to the court building, which is located at West Lafayette and Washington.
We'll see what develops. Interestingly, this court was where some suspected of being Islamic terrorists were recently convicted. Any correlation/causative link to this threat? Who knows at this point.
