CALIFORNIA: Four people died and two sustained injuries in a stabbing and robbery spree that occurred across several crime scenes in Southern California.

Police told US media the violence appeared to be random, with the only known motives for the two-hour rampage as “robbery, hate, homicide”.

“We know this guy was full of anger and he harmed a lot of people,” said Garden Grove Police Lt Carl Whitney.

Authorities have not yet named the suspect, a 33-year-old male.

The attacks come just days after the country was shaken by a pair of mass shootings in El Paso, Texas, and Dayton, Ohio, that left 31 people dead.

The stabbing spree took place across more than six locations over approximately two hours in Garden Grove and neighboring Santa Ana, about 35 miles (56km) southeast of Los Angeles.
