Police are searching for a California man who allegedly attacked his former girlfriend and two children with a hammer in a violent rampage early Friday morning.

The assault left the woman, 7-year-old girl and 8-year-old boy with “major injuries,” the Sacramento Bee reports.

All of the victims were rushed to a hospital, where they remained in critical condition as of Friday.

The violence came after the suspect, 23-year-old Deandre Chaney Jr., got into an argument with the ex-girlfriend.

Chaney reportedly took the woman’s car after the attack, although police later found it.

Emergency responders were dispatched to the south Sacramento home around 6:20 a.m. Friday after the woman notified authorities that she had been assaulted. Given the extent of the injuries, crime scene investigators had to canvass the house and neighborhood for witnesses and evidence, the newspaper reports.

Chaney, who remained on the lam as of Friday night, reportedly has a violent criminal history. Police say he should be considered armed and dangerous.

If anyone encounters him, police advise not to engage with him but to instead reach out to law enforcement authorities.

Police say Chaney is an African American with a medium complexion who is 5 feet, 7 inches tall and weighs 165 pounds. He has long, black dreadlocks as well as tattoos above his eyebrows and neck.

He was last seen wearing blue pants and a white shirt.

Anyone with information about the case should call the Sacramento Police Department at 916-264-5471, 911 or Sacramento Valley Crime Stoppers at 916-443-4357. Callers can submit tips anonymously and could be awarded up to $1,000.
