A baby died after a monkey snatched it from its mother's arms, Indian police investigating the incident in the city of Agra, home to the Taj Mahal, said on Thursday.
The 12-day-old boy was being fed by his mother when a rhesus macaque monkey broke into the room late Monday, local deputy police chief Prashant Verma told AFP.
The monkey grabbed the infant and jumped away along several rooftops in a crammed district of the global tourist hotspot, he said.
Locals chased the monkey down after the mother raised the alarm, forcing the animal to abandon the baby's body on top of a building.
Verma said the infant was declared dead on arrival at hospital but the family refused to allow a postmortem and the cause of death -- whether from a fall, bite or something else -- could not be ascertained.
India has an estimated monkey population of 50 million and roughly 10,000 are believed to roam Agra, stealing goods, bothering residents and breaking into properties.
Incidents of attacks by macaques -- a species with reddish-pink faces common across India -- are frequent in the city.
