Rumi and her second husband Zakir Hussain were beaten up by a hundred strong mob outside a Karimganj hotel, where the MLA had gone to meet up her father, on Friday night.
Rumi is at the centre of a bigamy row after she left her first husband Rakesh Singh and their two years old daughter in May this year and eloped with Hussain, a Facebook friend, converted to Islam and married him.
Her act has earned anger of various groups that say she betrayed her electorates. Rumi was prior with the BJP, but defected to the Congress later.
In the meantime, prohibitory orders under Section 144 have been clamped on Karimganj that remains tense after the incident.
