In a tragic incident in central west New South Wales, three individuals lost their lives and a fourth person sustained serious injuries in a shooting.

The suspect is reportedly still at large in Lake Cargelligo, prompting police to advise residents to remain indoors for their safety.

Authorities responded to an emergency call at around 4:40 p.m. on Walker Street, near Yelkin Street, where they found two women and a man deceased.

NSW Police have set up a crime scene and have launched an investigation to uncover the details surrounding the incident.

Officials are urging the public to steer clear of the area, while asking local residents to stay inside their homes.

“The public is urged to avoid the area and for local residents to stay inside.

“More information will be provided when it becomes available.”

Local MP Roy Butler said it was a “tragic” situation.

“It’s a terrible situation, and it’s still live, so we don’t have much information,” Butler said.

“My thoughts are with the victims and their families.

“Please stay indoors until the advice changes.”
