"This wasn't a large event, It was something very small, contained, and controlled," said FBI spokesperson Dave Joly.
Borders released the following statement:
"We take the safety of our employees and customers very seriously. To that end, we are cooperating with authorities to the fullest extent as they investigate this incident."
Bomb squad officers and other authorities were dispatched after the devices were spotted Saturday at the bookstore in a mall in the Lakewood area. The discovery was made after police responded to a report of a break-in.
The FBI says the two “small, crude devices” caused minimal damage in a small area in the bookstore, but no damage to the mall.
FBI agents are investigating the case.
