An adult leopard is trapped at Gopalpur tea estate in Alipurduar district on Sunday morning after a vigil of nearly a month.

Sources in the garden said that cattle had been disappearing from the Mohonpur division of the garden for nearly a month.

“Foresters were alerted and they started keeping tabs,” said a source.

A worker had been attacked by the leopard in a section of the tea garden about a month back, but workers and foresters could not spot the animal then.

A few days back, tea garden workers, while plucking leaves, came across pug marks. Foresters were informed, and a couple of days ago, they set up a cage with a goat as bait, said a source.

The leopard was finally trapped early on Sunday morning after which foresters tranquillised it. Deepak M. divisional forest officer, Jaldapara wildlife division, said the animal was released in Jaldapara forest after preliminary treatment.
