INDIANAPOLIS -- Indianapolis Metropolitan Police Chief Paul Ciesielski said Thursday that an internal affairs investigation has been launched regarding a woman's claim that she was violently arrested, resulting in a miscarriage.

LaDonna Dixon, 25, was arrested on Indianapolis' east side in June 2009 after police said she interfered with medics trying to treat her friend who was having medical problems, 6News' Joanna Massee reported Wednesday.

Dixon said that she refused to go inside her house and talked back to Officer Scott Childers, who she claimed beat and kicked her repeatedly as he arrested her, even though she told him she was pregnant.

"(I was afraid I was going to lose the baby) because of the way that I was getting thrown around. You know, slammed to the ground and kicked," she said. "I was like, basically, trying to protect myself, but I couldn't because I was handcuffed."

Dixon, who said she had taken a home pregnancy test, said she had a miscarriage inside the Marion County Arrestee Processing Center shortly after her arrest.

After she was released, Dixon went to Community Hospital East, but medical records did not indicate a pregnancy. The police report of the incident does not mention Dixon being pregnant.

Police declined to release additional details of their investigation.

"It is the practice of the department to withhold comments during the time which an internal investigation is being conducted and when litigation is pending," Ciesielski said in the release. "Upon conclusion of the internal affairs investigation, we will share the results with the community as appropriate."

Dixon's attorney, Everett Powell, said obstruction and resisting law enforcement charges in the case were inexplicably dismissed and that it's unclear if police ever investigated the incident.

"When I came on to the case and hearing what happened I was very disturbed. But what disturbed me even more was their response to it," Powell said. "This is not a mistake. This is not someone accidentally hitting someone."

Public Safety Director Frank Straub told 6News' Joanna Massee on Thursday that the department will examine the history of the case.

“We're trying to determine right now -- because I wasn't here and the police chief wasn't here -- exactly what was done when that allegation came out,” he said. “If we need to be critical of what we did or didn't do last year, we will do that because we are an open, transparent organization.”

Childers has no disciplinary record, only commendations, police said.
