The backstory:

According to a criminal complaint, police responded to Maple Grove Hospital on Feb. 5 on a report of an assault. When officers arrived, Field's wife was in labor, in the bathroom of her delivery room in the bathtub. The complaint states Field was in the doorway and starting to yell at her.

The complaint states a witness said she wanted Field to leave and while she went to get a nurse, he allegedly moved past her, shoved her out of the bathroom and shut the door to lock himself in with his wife.

The complaint states the witness said Field’s wife was living with her mom at the time, and Field could be at the delivery of the baby as long as he behaved himself. When he arrived, he was immediately aggressive with her mother and was kicked out. He came back a second time after saying he wouldn’t argue or yell, and his wife was in the bathtub. He started to yell at her. When the woman’s mother went to get nurses, Field allegedly attempted close and lock the door.

The complaint states his actions and communication with staff forced Maple Grove Hospital to go into lockdown.
