The probe was based on the complaint she submitted to the Navy Chief recently, official sources said, adding it started a few days ago.
The matter came to light yesterday after she filed a complaint with local Harbour Police, which registered a case against 10 people, including her husband, under Section 498 of the IPC based on the complaint filed by the woman on April 4.
The Kerala High Court had also sought a statement of the facts of the case on a bail application filed by the accused.
It said the officers, accompanied by their respective spouses, had only tried to unsuccessfully resolve the issues of the couple's personal life, it said.
