A Chattanooga Police officer has been arrested for domestic assault in Collegedale.
A police spokesperson said Officer Day has been relieved of duty pending the investigation.
Christopher Stephen Day, 26, was taken to the Hamilton County Jail after the Saturday incident.
A man told police he was walking to her car when he heard a woman scream out, "Please stop hurting me."
He said he then saw a woman crying and carrying a baby carriage. He said the woman told him that her husband had gotten angry and swung the carriage around with the baby in it. Then she said he grabbed her by the arm and dragged her across the floor.
The wife of Day told police they began arguing over who was going to stop to pick up food. She said Day called her a b---- and told her to shut up and get in the car. She said when she said she was no longer going that he threw her keys and began hitting the dining room table with his hand.
She said he then tried to take the car seat with their child in it from her. She said he finally let go, then put his hand over her throat.
She said afterward when he found she had called his mother he came running up the stairs, roughly put the car seat on the floor, and began to drag her on the floor. She said he then ran out the door.
Day had recently gone back to patrol after serving a year in the teleserve division after an incident involving a person who was in custody.
