The La Martiniere Schools issued orders on Monday morning, a day after a monitor lizard was rescued from the girls' school, to clear both campuses of bushes and rubble.

The corner near the AJC Bose Road gate of La Martiniere for Girls, where the lizard was spotted on Sunday, is close to a garden with a flowerbed. There are also bushes, shrubs and some bricks lying in a pile in the corner.

"I have issued clear instructions to clean the area (where the lizard was found) of any unwanted growth or bushes and shrubs. It should be cleaned within a day or two and I will follow it up," said Supriyo Dhar, the secretary of the La Martiniere Schools. "All corners of both campuses must be cleaned and any rubble cleared within a week."

The Facebook page of the school was flooded with posts from concerned parents.

"It is a matter of concern, especially with younger kids, because they might not know how to react. But I believe the school is taking adequate steps," said a father whose daughter is in kindergarten.

The school authorities have asked students not to panic in case they spot an animal on the campus. "We have told the children not to panic if they see an animal but to keep away and alert a teacher," said Rupkatha Sarkar, the principal of La Martiniere for Girls.

Forest department officials trapped some civets from the campus on the Saturday. "Whenever their numbers multiply, we alert the forest department," the principal said.

The monitor lizard found on the campus was kept in a cage and handed over to forest department officials, who took it to the Rescue and Rehabilitation Centre at Salt Lake. "We will release it into the wild after two weeks," a forest official said on Monday.

Monitor lizards are not known to harm human beings but might attack if they feel cornered or threatened, an official said.
