A monkey entered a home in Malaysia and viciously attacked a 50-day-old baby, leaving him with serious injuries.

On Saturday afternoon, the baby’s mother placed him on a mattress in the living room and went to the kitchen to make some milk for the infant when she heard him crying loudly.

The 27-year-old woman rushed to the living room and found the baby covered in blood and a monkey standing beside him.

Just then, the woman’s husband, who had gone to a nearby hospital with their other child, returned. The couple then rushed the baby to a nearby hospital for treatment.

"The woman’s husband said he had just returned home from the store and was shocked to see his son covered in blood with bite marks on his right cheek, the back of his head and his abdomen. His stomach was bitten until his intestines spilled out," police officer Noorzainy Mohd Noor told local news outlet Harian Metro. (Google Translation showed)

"He then rushed to take her son to Seberang Jaya Hospital (HSJ) for treatment before he was transferred to Penang Hospital (HPP)," the officer added.

The boy has since undergone a minor surgery to repair his torn abdomen.

"The door of the house was locked and the window was not open, but it is believed that the monkey entered by shaking the door until the latch type lock opened," the officer said.

The monkey has been caught and shot dead by the local authorities, local outlet The Star reported.

The baby, who's still under treatment, will remain at the hospital for two weeks before being discharged.

The incident comes less than a month after a 5-month-old baby girl in Malaysia was viciously attacked by a wild monkey. Siti Nur Asikin Sulaiman was boiling milk for her daughter when she heard her daughter’s screams. She rushed to the bedroom and saw the monkey sitting on her baby and ferociously beating her. After chasing the monkey away, the woman rushed her baby to a nearby hospital for treatment. The infant was recovering at the time.
