INDIANAPOLIS (WISH) - An early Monday morning explosion disturbed the silence of downtown Indianapolis.
An explosion detonated by the Indianapolis Metropolitan Police Department bomb squad because of what they found on the Federal Courthouse steps.
On the southwest corner of the old Federal Building at Meridian and Ohio streets downtown, about 2:40am, a backpack was found sitting on the steps.
IMPD PIO Michael Hewitt gave credit to a security guard on duty at the time.
"This is just a very observant security guard, here working in the area. Doing his or her job," Hewitt said.
Police were immediately called and brought in a bomb sniffing dog.
"The dog smelled something. What they thought could be explosives inside the backpack," he said.
So the decision was made to detonate the backpack.
First, police at the scene notified area hotels that they would soon hear a loud explosion. And the few people inside the Federal building were evacuated.
Just before 5 a.m., with the area clear and secure, a member of the bomb squad yelled the warning, fire in the hole.
And a loud explosion followed.
After the explosion, investigators say they found fireworks and a pipe with either marijuana or some other drug residue inside the backpack. Now, police need to find out who put it there.
"Apparently there was a large group of juveniles, that was around in the area, just not sure who left it there at this time," Hewitt said.
Police say the residue in the pipe is what likely triggered the bomb sniffing dog's response to the bag.
Police did not have any suspects as of 3 p.m. Monday.
Investigators are looking at the possibility there might be surveillance video in the area that would help figure out who dropped the backpack on the steps.
A winter storm warning is in effect for most of Central Indiana.
It's very rare that a single person can reach across national, racial, and spiritual borders to bring such hope and healing.
Dispatchers with Indiana State Police say a vehicle left the roadway Thursday night off of Interstate 69.
