A man in Australia allegedly went on a stabbing spree killing his two-month-old granddaughter and seriously injuring his wife and the infant's mother. The man, in his 50s, was also injured in the incident.

The baby girl was rushed to Lady Cilento Children's Hospital in Brisbane and the adults were taken to Princess Alexandra Hospital for treatment, a Queensland Police spokesperson said. The baby girl died at hospital. The incident occurred at around 2.30pm local time on 6 January in Parkinson suburb, that lies south of Brisbane.

Police were called in after the baby's mother managed to escape from her home in Watheroo Place to a neighbour's house in nearby Mapleton Court, which police have described as two separate crime scenes. "One of the victims went to the secondary crime scene and that's where police were notified from there," acting police inspector Sean Mackay was quoted as saying by ABC.

Shortly after the stabbing incident, more than 20 police officers and detectives arrived at the two places. Police cordoned off the areas in Watheroo Place and Mapleton Circuit in Parkinson.

"I was outside feeding my dogs when I heard the screams, they were very loud. I ran outside down the street then and I saw him [the grandfather] walking down the street before the police arrived," an eyewitness Sun Gill was quoted as saying.

"We don't talk to them really, it's the first time anything really has happened here. When I saw him outside, he was losing a lot of blood," Gill added.

"It was pretty surreal. Very, very surreal, just the blood itself, they had the garage door open. You could see all the blood in the garage and then the trail from when they walked to the neighbour's house," he stressed.

Police are investigating the case to figure out what exactly led to the stabbing.
