OXFORD, Ohio -- A hospital spokesman said a man has died five days after he was subdued outside a bar near Miami University by a police officer using a stunning device.

University Hospital spokesman Don Crouse said 24-year-old Kevin Piskura of Chicago died shortly after 5 p.m. Thursday at the Cincinnati hospital.

Police said Oxford Officer Geoff Robinson used the device early Saturday morning as he tried to break up a fight. Police said Piskura argued with police after a friend was escorted from a bar.

Piskura was heard screaming as police shocked him outside the Brick Street restaurant.

Witnesses said the officer drew his Taser gun and told Piskura to stop, and when he did not, the officer used the device.

Piskura was a 2006 Miami graduate. He was also a Benedictine High School graduate.

The Butler County offices of the sheriff and prosecutor are investigating the officer's actions.
