Roshni Raut, a close associate of Damania, told PTI, "Damania ended her strike after she received a message from Chief Minister on her mobile informing her that a proper inquiry has been constituted."
"The former AAP leader was also informed that a committee would be formed very soon to speed up (the probe) and ensure the time-bound investigation, following which she (Damania) decided to end her fast," Raut said.
She had also demanded a time-bound inquiry into the matter led by a retired High Court judge.
