The Calcasieu Parish Sheriff's Office executed a warrant on Tuesday, but at the wrong home, according to KPLC.
Police were looking to arrest Jacoby James, who is wanted for domestic abuse battery, theft, and more.
The homeowner said police pulled up with "guns drawn, lights on." Officers put handcuffs on the woman and walked her to the corner of the street.
The man they were searching for was not there and had never been. The homeowners are a former teacher and her husband, a reverend. Also inside were the couple's two grandchildren.
CPSO said officers obtained a no-knock warrant, but deputies saw people inside the home. Carol Weston, the homeowner, said her granddaughter saw police outside and they opened the door.
Weston said she was detained for about 20 minutes while deputies searched the home.
CPSO Sheriff Tony Mancuso met with the homeowners after the incident, and said the department has launched an investigation to find out how this happened.
"We should not make mistakes like this," Mancuso said. "It is our responsibility to do our due diligence to check and double-check and we were just wrong. We made a mistake and it embarrassed these two people who are great citizens of our parish who did nothing wrong and I want people to understand that we are sorry if we caused them any embarrassment and I hope they forgive us and this department and I am sorry. It is our job to make sure these mistakes don't happen and I hope it doesn't ever happen again. We will do everything we can to make sure it doesn't. I just want to apologize. "
