The 7am shift was then cancelled, leaving more than 1,000 arriving workers locked out as rangers with tranquillisers tried to corner the leopard and catch it. The 3pm day shift following was then also cancelled.
Eventually, after an operation that meant production was halted for nearly a day and a half, the beast was caught by wildlife department rangers.
Once the dart was shot into the animal, Vinod Kumar, conservator of wildlife for south Haryana said: “It will take 20-30 minutes for the leopard to calm down.
“The team members saw the leopard in CCTV footage and grabbed the opportunity to fire the tranquiliser at it.”
The wildlife team then removed it from the plant, he added.
