Lewis and Clark County sheriff's deputies say a man in Lincoln threatened emergency responders who were called in by a friend when the man started having convulsions.

Court papers indicate Dennis Jacob Doll demanded EMTs get out of his house.

Deputies report the friend followed him to a room to make sure he was safe after he fell and convulsed several times.

Deputies say Doll produced a firearm, “racked the slide” and pointed it at the friend.

Officials say Doll refused to leave the house; deputies surrounded it and used a phone and a PA system to try to talk with him.

After several hours, he walked out with his hands up and was arrested.
