Three brothers are charged with raping a 10-year-old Louisiana girl who locked herself in a bedroom when they offered her money for sex, police said.

Two of the suspects, identified as Raul Paz-Perez and Wilmer Paz-Perez, both 35, were arrested Saturday on a charge of first-degree rape involving a juvenile under the age of 13, Kenner police said.

A third brother, 31-year-old Elder Paz-Perez, is still being sought as of early Tuesday on the same charge, Lt. Michael Cunningham told The Post.

“We don’t know where he is,” Cunningham said. “He may be out of state.”

Elder Paz-Perez is the boyfriend of the 10-year-old girl’s mother. He and his brothers had been living with the girl and her family, including her 15-year-old sister and two stepsiblings, at the time of the alleged attack, Cunningham said.

The three brothers were alone with the 10-year-old girl at a home in Kenner on Wednesday when they made sexual advances toward her, offering her money for sex acts, Cunningham said.

The young girl locked herself in a bedroom, but one of the brothers managed to bust inside, Cunningham said.

“After defeating the lock, the three entered the room, undressed the victim, held her down and sexually assaulted her,” Kenner police said in a statement.

Days later, the girl told a relative, who then reported the alleged attack to authorities on Saturday. Raul and Wilmer Paz-Perez were arrested later that day, police said.

Detectives are also looking into whether Elder Paz-Perez sexually assaulted the 15-year-old sister of the 10-year-old girl after she “made a disclosure” to investigators about an incident a few years earlier, Cunningham said.

Two stepsiblings of the 10-year-old girl are also being interviewed by detectives to see if they were victimized as well, Cunningham said.

Raul and Wilmer Paz-Perez were being held without bail Tuesday at the Jefferson Parish Correctional Center, online records show.

Immigration and Customs Enforcement detainers have also been placed on Raul and Wilmer Paz-Perez, who are originally from Honduras and were in the US illegally. The immigration status for Elder Paz-Perez was unclear early Tuesday, Cunningham said.
