Gun men stormed her Ajari ward residence in Damaturu late friday and set it ablaze. The house was first attacked six months ago during which the occupants were robbed of their jewellery.
Police reports say the militants asked all the occupants of the house to leave the building before setting it on fire.
No casualties have been reported on the attack.
Police Commissioner Patrick Egbuniwe confirmed the incident, saying, the gun-wielding men stormed the house on Gashua Road and ordered all the occupants out before setting it ablaze.
He said: ”We got a report that the house of the mother- in-law of Governor Ibrahim Gaidam was burnt down by unknown gunmen suspected to be members of the Boko Haram sect.
“When they got to the house, everybody was asked to come of the house before they finally set it on fire. No life was lost.”
