Man charged with threatening DA

LAWRENCEVILLE - A Duluth man was arrested Monday for charged with making threats against Gwinnett County District Attorney Danny Porter last week, prompting authorities to place Porter and his family under surveillance.

The Gwinnett County Sheriff's Department fugitive squad tracked Robert Ashley Walker to his Duluth House about 5:50 p.m. and arrested him when he left to take a walk with his wife, said department spokeswoman Stacey Kelley.

Walker is charged with intimidation of a court officer and terroristic threats and acts. He is being held at the Gwinnett County Detention Center in Lawrenceville.

When Porter was told Thursday about a verbal threat by Ashley that had been made against him, he recognized Ashley's name as someone who had been prosecuted through his office in the past. Ashley was convicted in 2003 of carrying a concealed weapon and aggravated assault and spent some time in the Gwinnett County Detention Center.

Authorities decided to take the threat seriously, and Porter was placed under protection by the Gwinnett County Police and Duluth Police departments.

In a telephone interview Saturday, Porter said he had to curtail some activities and make arrangements for officers to accompany him to others while the threat was being investigated.

"I'm mad. I don't like it," Porter said Saturday. "I don't like things that put my family in danger."
