WINONA, Minn. – A police officer was injured attempting to take down a man in a street arrest when one foot became twisted in the grate of a storm sewer. The Police Department didn’t release the officer’s name but said the injury was painful and severe. The officer was taken to the Winona hospital. The incident, about 11:20 p.m., began in just east of downtown on Second Street. Police responded to a report of a man and woman fighting in a parking lot. The pair — Xavier Gage Mercer and Anastasia Marie Smith, both 18, both from Winona — denied fighting. Mercer turned uncooperative and stand-offish when officers, smelling alcohol, asked if he had been drinking. According to the police write-up of the incident: Officers tried give Mercer a breath test and he became combative. He pushed an officer in the chest and began screaming. Smith slapped another officer in the face and gabbed an arm. In trying to subdue Mercer, one officer’s foot got caught in the storm drain. Smith then slapped an officer in the face. Once Mercer was subdued, his blood-alcohol level tested at O.14% — almost twice the maximum allowed level. On Mercer’s person officers found marijuana and Jose Cuervo tequila.
