PORTLAND — The Portland man convicted in a race-motivated verbal attack on a black woman in an Old Port bar last year faces new civil rights allegations.

Attorney General Michael Carpenter on Tuesday sued Thore Aatlo for allegedly violating the civil rights of three more Portland residents, including Gerald Talbot, the city’s most prominent civil rights advocate.

The lawsuit, filed in Cumberland County Superior Court, alleges that Aatlo threatened violence and harassed Talbot, his daughter and his son-in-law with repeated racial slurs.

The suit seeks a court order barring Aatlo from future racial threats and harassment, and a $5,000 penalty.

Assistant Attorney General Stephen Wessler said Aatlo isn’t getting the message that his conduct is wrong.

“This case is about somebody who is acting upon his racism to threaten violence against people, and that in no way is protected free speech,” said Wessler. “His conduct is just outrageous and we’re going to make sure he doesn’t do it again.”

After a jury trial last year, Aatlo became the first person convicted in Maine of a race-motivated violation of federal civil rights law. He served a month in jail and five months of in-house confinement.

Wessler said the new allegations against Aatlo started the day after his sentencing in federal court.

Talbot and his daughter, Robin Bradley, picketed Aatlo’s jewelry shop with other NAACP members to protest what they believed was a lenient sentence. The state alleged Aatlo hurled racial slurs and made threats of violence at Talbot and Bradley.

The lawsuit also alleged that Aatlo harassed Robin Bradley’s husband, Jim Bradley, with whom he recently had a fistfight.
