WINONA, Minn. — A Winona man was arrested after two downtown shouting disturbances, one with a threat to kill officers who were trying to calm him down. Taken to jail was Matthew Ryan Ngyuen, age 40, who’s a familiar face at the jailhouse. The first disturbance was about 7:10 p.m. in the 50 block of West Second Street. One 911 caller said a man was proclaiming to be on drugs. A second caller said the man was screaming for a girl named Allie. The officers gave this further account: When they arrived, Ngyuen said he didn’t need help. Then he charged at the officers. With his hands in his waistband, he said he would kill them. He was also identifying himself as Martin Luther King. The officers, who have continuing experience with Ngyuen and not believing him armed, decided to de-escalate the situation. They told Ngyuen to move along. They backed off and cleared the scene. Following up 10 minutes later, the officers found Ngyuen at Third and Center streets and screaming into a stranger’s face. The officer told Ngyuen again to move along. With clenched fists, he charged the squad car. The officer in the driver’s seat rolled up his window. Ngyuen head-butted the window twice. The officers got out of their car and told Nguen he was under arrest. They cuffed him despite resistance, but he managed to head-butt the hood of the squad car and spit in one officer’s face. The officers managed to pull a spit hood over Nguen’s head for ride to jail.
