The employees we spoke with at Iron Workers Union 321, said they cleared more than 200 pounds of glass and said it was a senseless crime.
Other employees at OW pizza said their minds raced when they saw the damage that greeted them at work Friday morning.
"It looks like we've been robbed because there's stuff everywhere," said Tara Collins.
It turns out they weren't robbed and instead the vandal had allegedly went down 2nd and 3rd streets in downtown Little Rock throwing bricks and rocks through any large plate glass window they came across.
"They busted out three major big windows," said Collins. "Just really scary, I don't know why they'd do such a thing."
"An angry individual," said Robert Garmoe, "Who just started knocking out windows."
Garmoe works at the Iron Workers Union and said he and two other workers were busy, not helping their union members today, but with cleaning up the mess left by the vandal.
Garmoe said it hurts him to know the cost to fix the damage will come straight from the pockets of union members
"That's gonna have to go back to replacing the windows," he said.
Both employees we spoke with said even though nothing was stolen, this is a big hit.
"Very annoying," said Collins, "And it just hurts my heart because they don't know the damage they do and the people who have to come in and clean it up."
But all things considered, they told KARK it could have been a lot worse.
"After work hours there's people in the building that could have been injured by one of the bricks going through the windows," said Garmoe.
Witnesses said they saw Little Rock Police take someone into custody at the E-Z Mart on Markham.
