A Montana city is on lockdown after four people were killed in a bar by an active shooter.

Anaconda is currently under a shelter-in-place order following an incident where a suspect, identified by law enforcement as Michael Paul Brown, 45, reportedly discharged a firearm inside the Owl Bar on Friday.

One person who spoke with MTN News said they had been at a nearby bar and saw the shooter walking around with a rifle.

Brown is armed and dangerous, according to The Anaconda Deer-Lodge County Law Enforcement Center which released an image of him amid the manhunt.

Officials said that he was last seen wearing a tie-dyed t shirt, blue jeans and an orange bandana. 

Police said they pulled over the driver of a white Ford F-150 after chasing after the vehicle, but Brown was not inside the vehicle.

SWAT teams also raided Brown’s property, but he was not inside. According to records Brown’s home is directly adjacent to the bar.

The local sheriff’s office is urging residents to remain inside and stay ‘vigilant’.

The suspect was last seen in the Stump Town area, which is just west of Anaconda, according to the Anaconda-Deer Lodge County Law Enforcement Center.

He was believed to still be armed, the Montana Highway Patrol said in a statement.

The Montana Division of Criminal Investigation, which is leading the investigation, confirmed four people were pronounced dead at the scene.

More than a dozen officers from local and state police converged on Stump Town where they appeared to be searching for the suspect in the woods.

The owner of the Firefly Café in Anaconda said she locked up her business after getting alerted to the shooting by a friend. 

“Being in Montana, firearms are a familiar aspect for us. However, having our town on lockdown is quite unsettling for everyone,” café owner Barbie Nelson explained to the Associated Press.

‘It´s a small town, so we all probably know someone who was there’ at the shooting. she added.

NBC Montana reporter Josh Margolis shared an image of a SWAT team near the bar shortly after 1pm Mountain Time.

‘Authorities are searching for a suspect believed to be armed. Please avoid the area.’
