Werribee police locked down the Hoppers Crossing street, telling residents to leave their homes, before blocking all access to the street after reports of a domestic incident.

Homicide detectives said a 40-year-old woman was stabbed to death, with witnesses reporting they saw a woman with a neck injury leave the property.

Police have not released the name of the woman, who coll

apsed on a nature strip outside a home in Sandleford Way about 3.30pm.

Police said several motorists stopped and attempted to assist, but she died at the scene before emergency services arrived.

Homicide detectives charged 37-year-old Glenroy man Jason Hawkins on Friday night with one count of murder and he was remanded in custody.

A resident, who did not wish to be named, contacted the Banner on Friday afternoon, saying the incident had left her scared and shaken.

"They [the police] told everyone to leave the street, but

we couldn't leave because we don't have a car and I've got kids here.

"I was allowed to stay here and they just told us that someone died and we need to stay in the house and lock the house up."

The resident said five police cars had surrounded the home around 3.30pm and two ambulances attended. She had not directly seen the incident, but had heard "noises" in the street.

"We just got told to stay in the house and don't leave the house, lock the house up and just stay there. But the rest of the people in the street, they all had cars so they all got told to go.

"I was feeling pretty scared."
