Both Moti and Champa were chained for about seven years ago, because of their "volatile" nature.
However, after a petition filed by an organisation working for animals rights, the Madhya Pradesh High Court directed the Indore Municipal Corporation (IMC)-run Kamala Nehru Zoo authorities to unchain them and construct an open enclosure for them.
"Construction of an open enclosure at an estimated cost of Rs 50 lakh began about a week ago," zoo in-charge Uttam Yadav told PTI.
The elephants have been in the zoo since the last 25 years and whenever the male elephant Moti was unchained, it attacked people and had also seriously injured a mahout.
While hearing the petition, experts opined that because of their volatile nature, Moti and Champa could neither be set free in the zoo, nor released in the forest, since they are not used to forest life.
