Steven Shaffer, owner of Shaffer's European Bakery in Collegedale, was arrested Friday on charges of arson and filing a false police report, according to the detective who investigated the case.

Detective Kat Cooper of the Collegedale Police Department had been investigating Shaffer since the Valentine's Day arson at his bakery. Shaffer said at the time he had gone into work that day to check on the bakery. He said two men broke in, assaulted him with a box cutter and set the bakery on fire.

Cooper, who said she conducted a "lengthy, careful" investigation, said a number of red flags popped up as she investigated.

"There was enough physical evidence surrounding the incident that I was able to develop enough probable cause for warrants to be signed," Cooper said.

Cooper said Shaffer was indicted by a Hamilton County grand jury Thursday, and the arrest was made by the Collegedale Police Department on Friday afternoon. She said he was picked up by the Hamilton County Sheriff's Office for transport to the Hamilton County Jail.

The Hamilton County Jail had no information regarding Shaffer's booking as of Friday evening.

Shaffer, a senior at Southern Adventist University, had received significant support from the Collegedale community after the arson. A GoFundMe.com page created to raise money to restore the bakery raised nearly $4,000.
