LAFAYETTE, Ind. (WLFI) — A Lafayette police officer is in serious condition after being shot in the back by another officer Tuesday morning, LPD confirms. The officer, Lane Butler, is a three year veteran of the LPD. She is currently listed in serious, but stable, condition.

According to Lafayette police, officers were responding to a complaint of criminal mischief at 813 North 9th Street, Apt. 2 around 10:50 a.m. Police were checking to see if a person wanted on a warrant was at the apartment. The resident was cooperative and allowed officers to search her apartment to show them the wanted person was not there. A large dog was in a cage inside the apartment, and the woman told officers this before they entered.

Butler, and two other officers, then entered the apartment to look for the wanted person. During their search, the dog broke free from the cage and caused the officers to leave the apartment to avoid the animal. As they fled out the door, an officer's gun discharged. The bullet went through the apartment door and hit Butler in the back. Police said she was wearing a protective vest, however, the round struck her above the protected area.

Butler was taken to the hospital. Chief Patrick Flannelly was with her and her family

Animal Control currently has the dog, according to police.

"It's a very difficult day for the Lafayette Police Department," said Phillips. "One of our own was injured today. There are many unpredictable variables anytime, as a police officer, you are out responding to calls. You never know what you are going to encounter."

Police are expecting to release body camera footage later in the week.
