DENVER (Reuters) - A man suspected of planting two bombs at a Borders bookstore in a suburban Denver shopping mall over the weekend is in custody on unrelated charges, police said on Tuesday.
Jonathan Lawless, 30, is the "prime suspect" in the June 25 bombing at the Colorado Mills Mall, Lakewood Police Chief Kevin Paletta told reporters.
Lawless was arrested later that day by the Colorado State Patrol on suspicion of drunken driving and resisting arrest in a neighboring county, he said.
Federal law enforcement is in charge of the bombing investigation but Paletta said he wanted to reassure the public that the suspected bomber was off the streets.
The FBI said a store alarm was triggered early Saturday morning at the mall and "two small crude devices partially functioned" inside the bookstore.
The homemade explosives did minimal damage to the store and no one was injured.
A spokesman for the U.S. Attorney's Office in Denver said there would be no information released on Tuesday regarding the filing of criminal charges against Lawless in federal court.
Paletta said investigators believe Lawless acted alone and did not specifically target the bookstore.
"(Lawless) is not connected to any extremist or terrorist group," he said
