The one-month-old, Muhammad Isyraffie Daniyal Annur Rosmadi, had been left lying on a mattress at home in Butterworth, Malaysia, while his mum was in the next room preparing a snack.
All of the doors and windows were closed, but somehow the monkey found its way in and attacked the tot, biting him repeatedly
The lad’s mother returned from the kitchen to find her son covered in blood, a yard away from the mattress he had been left on.
Noorzainy Mohd Noor, as assistant commissioner from North Seberang, said that officers had been called to the scene and, he told reporters, "initial investigations revealed that there were bite marks to the child's head, stomach and cheek".
"The baby boy had just woken up and was placed on the mattress in the living room, while his mother was in the kitchen preparing milk," he said.
"At the time of the incident, his father was at a nearby sundry shop, while his grandmother was in the kitchen."
The attack happened while the little lead was on his own in the room.
He was sent initially to the Seberang Jaya Hospital for emergency treatment before being transferred to Penang Hospital, where surgeons operated on his stomach the following morning, January 10.
"Doctors needed to stitch up the bite marks,” said Asst. Commissioner Noor, “the operation was to stitch up torn skin as a result of the bites.”
A monkey seen fleeing the scene was identified as a large hairy male that had often been seen lurking around the area.
Assistant Commissioner Noor said although the animal raided homes in the area looking for food on a number of occasions, this had this was the first time it had attacked a human. "Previously, the monkey only made noise at children and the elderly outside their houses.
He added that he had "alerted the Wildlife Department to catch the monkey".
