UPDATE: A SWAT situation on Memphis Drive was resolved after a two-hour standoff Sunday night.

It all started with a call to police about a disorder involving a weapon.

Lt. Austin Garrett stated, “once officers arrived on the scene they spoke with witnesses and confirmed that shots had been fired inside the residence. While they were there, they were interviewing witnesses, they observed shots fired inside the residence."

That's when Lt. Garrett said SWAT, the hostage negotiation team (HNT), and Chattanooga police set up a perimeter around a home in the 3900 block of Memphis Drive.

Chattanooga police responded to the address around 4:15 pm Sunday. According to an arrest affidavit, a woman who knew the suspect, Dwight K. Land, said Land was hallucinating and firing a firearm inside the home.

Land did surrender to police.

Lieutenant Garrett says the way the situation was handled is how the department strives to handle all incidents.

“The good thing is that it was resolved successfully, no one injured, and we don't believe he was firing shots at us. That's not been completely determined yet, but when the officers were there they believed the shots were being fired randomly inside the house, but he is in custody. No one has been injured,” stated Lt. Garrett.

During a search of the home, officers found a baggie containing an unknown white powder, the affidavit explained.

Land faces charges of felony reckless endangerment, disorderly conduct, possession of controlled substance and possession of drug paraphernalia.
