The state Ethics Commission is investigating why the former State Police colonel allowed the arrest report of a judge's daughter to be altered, according to The Boston Globe.

That scrubbed report led to the early retirements for the top two commanders of the State Police, as well as lawsuits filed by the two troopers who were asked to redact comments from the document.

The head of the State Police union confirmed the Ethics Commission investigation to The Globe, the newspaper reported. Troopers Ryan Sceviour and Ali Rei were apparently interviewed by investigators this week.

However, an Ethics Commission spokesman told The Globe that he could neither confirm nor deny if an investigation was underway.

Alli Bibaud, the 30-year-old daughter of Dudley District Court Judge Timothy Bibaud, was arrested in October for drunken driving and possession of heroin. She allegedly made comments about her father being a judge and also about trading sexual favors for drugs, which were ordered to be removed from the report.

Gov. Charlie Baker maintains that the order to redact the report came from former Col. Richard McKeon and that the troopers involved did nothing wrong.

Attorney General Maura Healey has launched an investigation into the actions involving the report, as has new State Police Col. Kerry Gilpin.

"There are a lot of unanswered questions and that's part of what our investigation is going to get to the bottom of," Healey said during an appearance on WGBH's "Boston Public Radio" show earlier this week. "People want and deserve answers. There are obviously serious allegations raised here."

Gilpin will also review applicable policies and regulations regarding police report alterations, a State Police spokesman said.

Officials are also investigating communications between State Police and the Worcester County District Attorney's office regarding the report.

McKeon and Lt. Col. Francis Hughes resigned in the wake of the scandal.

Bibaud pleaded guilty to operating under the influence of liquor and several motor vehicle violations in Framingham District Court earlier this month.
