The abrupt departure of Birmingham's interim police chief comes a week after a woman filed a request for a protection from abuse order against him.

The request was made against 55-year-old Orlando Wilson by the mother of his two children. She filed the request on April 11 in Jefferson County Family Court, and the records were made public in the online court system on Tuesday.

The request claims potential sexual abuse of a young girl, and possible physical abuse of a young boy. According to the records, one of the incidents reportedly happened in 2013 and the other in September of 2017.

Court records do not reflect any criminal charges against the longtime police veteran.

It does not appear that a protection from abuse order was signed by a judge. Two judges recused themselves, one of whom explained because of his longtime close association with the police department.

In the proposed order, the woman asked Wilson be restrained from having physical or violent contact with her or the children either at home or at school. The woman also asked that Wilson be restrained and enjoined from harassing, stalking, annoying, threatening or engaging in contact that would place (her) in reasonable fear of bodily injury.

In a statement sent on Wilson's behalf on Thursday, attorney Jacqueline Smoke said the allegations were "false and defamatory" and stemmed from a battle between Wilson and the mother over custody and child support.

"There has been history of false allegations not rooted in fact from this woman," the statement read.

Smoke said Wilson is leaving the office because he has long needed surgery.

"The transition has nothing to do with a petition for protection from abuse containing false allegations of abuse that he had no knowledge existed," the statement read.

AL.com asked the Trussville Police Department two weeks ago about a possible investigation into alleged wrongdoing by Wilson but they denied any knowledge of such.

On Thursday, Trussville police detective Sergeant Michael Bruce shared with AL.com a report was filed with their agency on March 20, 2018 at 4:53 p.m. That report alleged sexual abuse of a child less than 12-years-old in December of 2013, though the child is now older than 12. The incident report list an address in the 3500 block of Valley Crest Trail. Online records indicate that Wilson lives at the address.

Bruce said the investigation into the incident is ongoing.

"During our investigation of the report filed with us in March of this year, we have been able to determine that she (the complainant) had reported the complaint to another agency in 2013," Bruce told the Trussville Tribune. "That information never made it back to us. She was under the impression that the agency would forward the complaint to us, but that never happened. As this is an ongoing investigation, we can't say much more at this point."

Shortly before 12:30 p.m. Thursday, Tuscaloosa County Circuit Judge Philip N. Lisenby, appointed by Alabama Supreme Court Chief Justice Lyn Stuart to hear the case, filed an order saying he had been assigned the case because all of the judges of the 10th Judicial Circuit have recused themselves.

Lisenby wrote that he has reviewed the allegations made by the woman and understand there are pending child support cases in the Jefferson County Family Court. "From the pleadings, it appears that the family court case is highly contentious regarding visitation, support, child support and allegations of contempt regard the parties two children who are now ages 14 and 12,'' Lisenby wrote. "It also appears that several agencies and professionals may have been involved with this family."

The judge noted that Wilson and the woman were most recently in court on March 6 and another hearing is set for June 6.

"The current petition makes serious allegations of abuse which occurred between seven months and almost five years ago,'' he wrote. Therefore, he said, he would not issue any orders without giving both parties an opportunity to be heard.

Earlier Wednesday, Birmingham Mayor Randall Woodfin announced that Wilson would be transitioning out of the position and leaving early to undergo a medical procedure. Wilson was at work on Wednesday.

The mayor's office was asked Wednesday night whether the court filing had anything to do with Wilson's exit, and spokeswoman Chanda Temple replied: "I have reconfirmed that he will have a medical procedure later this week which is why the transition has started."

Wilson came out of retirement from the Birmingham Police Department just two months ago when Woodfin appointed him as the acting chief while the city conducted a national search. The mayor announced earlier this week that he will interview three finalists for police chief next week.

Former police Chief A.C. Roper in November announced he was stepping down after 10 years on the job.
