ANDERSON, Ind. -  

An Anderson man has been arrested after investigators said he claimed to be a police officer and raped a woman in her home.

Terry Lee Duckworth, 66, was arrested Monday on preliminary charges of rape and criminal deviate conduct.

In July, Duckworth approached a 24-year-old woman and her 1-year-old daughter at a downtown park, struck up a conversation and walked with the woman as she walked home, police said.

When they reached the woman's home, Duckworth asked the woman if she needed money, alarming the woman, police said.

When the woman went to go inside, Duckworth followed her, forcing his way into the home and sexually assaulting the woman, police said. 

The woman was able to get away and escape to another part of the home, but Duckworth followed and sexually assaulted her a second time, police said.

During the attack, Duckworth told the woman that he was an Anderson police officer and that he was going to arrest her for battery and prostitution for soliciting him for sex in exchange for money, police said.

Duckworth told the woman she could get out of being arrested if she performed a sex act on him, which he then forced her to perform, police said.

"We take that very serious because the very nature of someone using our position to commit a crime is heinous; a crime like this is very heinous," said Anderson detective Joel Sandefur.

After the attack, Duckworth told the woman he was doing her a favor by not arresting her and he left the home, police said.

Duckworth was being held at the Madison County Jail.

Duckworth has a criminal history dating back more than 30 years, even including an arrest for murder. Duckworth is currently on parole until 2013 after pleading guilty to intimidation.

Police said Duckworth could have other victims who have yet to come forward.

Police want to remind people they have the right to ask officers for a badge, ID and even for uniform back-up.

"You can ask for a uniformed officer come to (a) location and have that officer positively identify (someone) as a detective," Sandefur said.
