BRUNSWICK, Maine — A Brunswick man was arrested early Thursday in connection with a racially charged e-mail sent to Gov. John Baldacci and at least one other member of the Maine delegation to the Democratic National Convention in Denver, police said.

The threatening e-mail from 38-year-old Manuel Aguilar was sent shortly after Democrat Barack Obama was declared the presidential nominee by acclamation, police said.

State Police Sgt. Glenn Lang, supervisor of the Maine Computer Crime Task Force, described the e-mail as “a very nasty racial e-mail that would’ve caused anyone who read it to have great concern.” But there was no specific threat against any individual, he added.

A member of the Maine delegation alerted police after she received the e-mail in Denver, said David Farmer, Baldacci’s spokesman. The e-mail was sent to a distribution list that included Baldacci, but the governor never received it because it was blocked by a spam filter, Farmer said.

Aguilar, who was arrested early Thursday in Brunswick, is charged with violating a protection order. Lang declined to elaborate on the protection order.

Aguilar was held in the Cumberland County Jail pending a court appearance Friday. He declined a request from The Associated Press to discuss the matter.
