Two 18-year-olds were taken to the hospital but expected to survive after a trio of assailants drove up and stabbed them around 7 p.m. on Tuesday, according to the Long Beach Police Department.

The attack happened while the 18-year-olds were walking with another person along Pacific Coast Highway near Sherman Place, which is just east of Cherry Avenue, LBPD spokesman Richard Mejia said in an email.

While they walked, three assailants drove up and stabbed the two 18-year-olds in the upper body, Mejia said. The attackers then drove off in a silver sedan, eastbound on PCH, according to Mejia.

Paramedics took the victims, one male and one female, to a local hospital to treat their wounds, which weren’t life-threatening, police said.

Police said they don’t know a motive for the attack and detectives are investigating.
