An Indiana inmate who said officers beat him in the Lake County Jail has been charged with attacking those officers. Michael Ryan McGill is already serving 27 years for his conviction on rape and criminally deviant behavior charges in attacks on a 16-year-old girl and a 52-year-old woman.

Now he faces battery and resisting law enforcement charges for the Jan. 12 fight. McGill, 21, alleged a group of officers beat him after he exchanged insults with them. A jail video did show a group of officers surrounded McGill and took him to the ground.

But an investigation determined McGill was the aggressor and that he broke an officer's arm during the fight, the Lake County Sheriff's Department said in a news release this week.

"When McGill became aggressive, correctional officers felt it necessary to take him to the ground for his own protection as well as that of the officers involved," the release said.

Police said the argument began when McGill was unable to get a mattress and some personal property he wanted. McGill repeatedly pushed the intercom button, banged on the window and began covering a surveillance camera in his section with wet tissue paper, a probable cause affidavit said. Officers then shackled and moved McGill from his section for a time. While officers were removing the shackles to take him back, McGill made an aggressive move toward one of the officers, who took McGill to the floor, the investigation showed.

McGill fought with the officer, biting and scratching. One jailer struck McGill once or twice in the head "trying to stun him and stop him from being bitten," the affidavit states. More officers then moved in to helped restrain McGill, who has since been transferred to a state prison to begin serving his sentence, the news release said.
