HUNTSVILLE, Alabama - A SWAT team is on the scene of a stand-off in Knox Creek subdivision off Balch Road, a mile from the Madison-Limestone county line. At least two people, including the barricaded subject, are inside the home in the 200 block, Huntsville Police spokesman Dr. Harry Hobbs said.

Police "feel it may be a domestic dispute," he said.

Hobbs could not say if someone inside the home had been shot.

"At this time, we can't confirm anyone has been injured in the residence," Hobbs said.

Negotiations are ongoing, Hobbs said.

"We have made contact with the suspect," he said, adding that police have contacted family members in hopes they can help work with the subject.

"We hope to bring this to a quick and safe resolution," Hobbs said.

The stand-off began after someone inside the home called police at 7:40 a.m. to report a "possible volatile situation," he said.

A portion of Knox Creek Trail, the main road through the subdivision, has been barricaded by police and Madison County Sheriff's officers, as well as portions of Sweet Hollow Road and Mountain Creek Drive. HEMSI ambulances are on the scene as a precaution.

Hobbs said police are grateful for the cooperation from Knox Creek residents as the situation continues. Residents in at least a block surrounding the home have been evacuated.

"We appreciate them allowing us to have the space to work this out," he said. "These things can take a while."

An al.com reporter is on the scene and will update this report as information becomes available.
