Police were at the Ross Adair Federal Building and Courthouse on Tuesday morning investigating what some say they were told was a suspicious package.
A bomb squad went to the federal courthouse and some roads were closed.
There were a number of people in the area, and a crowd gathered at intersection of Breckinridge and Harrison. Some were going to the TinCaps game, and some were waiting to go inside the courthouse.
More information will be posted as it becomes available.
In Indianapolis on Monday, authorities detonated what they called a suspicious bag that was found outside its federal courthouse.
Indianapolis police spokesman Officer Michael Hewitt said bomb squad investigators believe the back pack contained fireworks and drugs. He said the back pack was spotted by a security guard about 2:45 a.m. Monday along the sidewalk outside the courthouse that's a block from Monument Circle.
Hewitt said a police dog indicated explosives were present in the bag, leading to the decision to detonate it about 5 a.m. He said no threat had been made and police didn't immediately know who might've left the back pack there.
Streets alongside the courthouse were closed until after the bag was detonated.
