Sub-inspector Amitabh Arambam, a gallantry award winner, was allegedly dragged out of his personnel car and brutally assaulted by the speaker's escort personnel on May 10 night in front of his wife and two children for taking time to move out of the way and letting the speaker's convoy pass.
Th Lokeswar allegedly did nothing to stop his guards and drove off.
The central minister told them he was aware of the incident and as it was being investigated by the state government he was waiting for the actual facts, she said.
"The union minister assured my family members that he will see to it that justice is done," she said and urged the authorities to take up the matter "very seriously" so that the culprits were punished and justice was done, specially since they were state government employees like her husband.
The commander of the escort party was suspended after the incident and investigations into it are on, officials said.
