UPDATE: Elderly Man Accused of Setting Chattanooga’s Dome Building on Fire

Chattanooga Police say he took an axe to the historic Dome Building.

Bruce Garner with the Chattanooga Fire Department, says, "Busted out about 20 windows plus two glass doors."

Investigators say he then lit a fire inside.

Garner adds, "It looked like someone used accelerant like Coleman fuel, but fortunately the sprinkler system activated and it put the fire out."

While firefighters were on scene they noticed Maier just standing around.

Garner says, "He was trying to be concealed a little bit, he was trying keep from being seen."

Firefighters called police because of Maier’s suspicious actions.

That’s when officers saw a familiar face.

Garner adds, "Its odd to us of course that he would make another appearance and apparently set the building on fire again"

That’s right … again.

Court records show Maier committed the same crime in 2009.

He was actually on unsupervised probation when this incident happened on Saturday.

Garner says, "We don’t understand what his motivation is for doing damage to this building and setting it on fire twice, but we’re just glad we were able to apprehend him with the police departments help."

A Hamilton County court clerk tells us Maier pled guilty to his first arson charge, but couldn’t tell us how much jail time he actually served.

He caused more than $30,000 worth of damage this time around, and fire investigators hope the evidence will again work in their favor.

Garner adds, "Because he appears to be a fairly dangerous individual."
