A grieving mother monkey was pictured trying to revive her dead baby after it was killed by a car.
The primates were wandering along quiet mountain roads after coronavirus restrictions were eased in Prachinburi, Thailand.
National parks reopened yesterday and the increased numbers of cars proved deadly.
Wildlife rangers arrived at the scene and found the mum cradling the monkey before carrying it away into the woodland.
Vets tried to trace the family but the animals had already disappeared.
A national park officer said: ”The monkeys have ventured onto the roads during the pandemic as the national parks have been closed.
”With parks opening again, cars returned to the roads and the baby monkey was hit by a fast-moving vehicle.
”We would like to emphasise to tourists that there is no feeding of the monkeys, no littering and no speeding.”
Last month, disturbing footage emerged showing villagers hanging a struggling monkey from a tree as a warning to its troop to stay away.
Villagers in the southern Indian state of Telangana had chased off the marauding monkeys but one of them fell into a water well before escaping.
The thugs then decided to hang the animal from a tree to teach the troop a lesson.
In the disturbing video, the men allow their dogs to nip at the monkey as it struggles for air.
The helpless creature desperately tries to free itself as its life is sucked out of it.
By the end of the clip, the monkey appears almost totally limp but it ends before its death is shown.
