The rescue took place in torrential rain in the central province of Nakhon Nayok on Wednesday when a one-year-old elephant fell into a drain hole on the side of the road. The distressed mother stood guard over her calf, according to national park staff, but also fell in shortly after being drugged.

The calf began nursing its mother, who soon regained consciousness, and the two were immediately returned to the wild.

Sky News reported that Dr Chananya Kanchanasarak, Khao Yai National Park Divisional Veterinarian, said: “It was impossible to get close to the baby while the mother was around, so we gave her three doses of tranquilizers, but she went towards her baby before she passed out and hit her head.” An elephant calf stuck in a drainage shaft in Khao Yai National Park, Thailand.
