Four forensics officers have arrived at the scene of a homicide investigation after a death in Hamilton overnight.

One child at the property was killed and three other people have been injured.

Neighbours are congregating and watching police work, several brought to tears over the violence that occurred only metres from their homes.

Jesse, a local resident who said he was one of the first on scene told the Herald “I knew the baby was gone ... it was lifeless”.

He said he knew something was wrong when he saw a man dragging a woman across the street.

She said a nana and auntie arrived at the scene and “dropped to ground, screaming and bawling” after learning what had happened.

The children’s mother was injured and the alleged offender was also taken to hospital with injuries.

Police would not be drawn on specifics but other sources have spoken about what happened at the address.

It is understood the alleged offender’s injuries were self-inflicted.

“Emergency services were called shortly after midnight to Douglas Cres, Fairfield, after a report of an assault,” a police spokesperson said.

“When police arrived at the property, they found one person deceased and two others seriously injured, who were transported to hospital.

“A 34-year-old man was found a short distance from the address with serious injuries and was also transported to hospital, where he remains under police guard.

“A scene examination will take place at the property today.

“Police would like to reassure the community that this is an isolated incident and there is no ongoing risk to the wider public.”

The spokesperson confirmed the 34-year-old man will face charges in due course in relation to the incident.

Police, fire and ambulance have all attended the address and the cordon encompasses at least 10 houses.

Two paramedic bags, gloves and other tools are strewn across the front lawn of one property, which has police tape across it inside the cordon.
