Police are trying to figure out why four men were stabbed late Saturday as they left a wedding reception in downtown Half Moon Bay, investigators said.

The victims, four Hispanic men in their 20s, had just walked out of the IDES hall on Main Street when they were approached by two attackers about 11:20 p.m. The men exchanged words with the assailants and were stabbed, according to the San Mateo County Sheriff’s Office. No one was arrested and a motive for the attack remains unclear.

The victims were rushed to the hospital in critical condition, but are expected to survive, police said.

The Sheriff’s office said the attackers were both Hispanic men. One appeared to be 18-20 years old, 5 feet 5 inches tall with light skin and a chubby face. He had black short crew cut hair. The other man was 5 feet 10 inches to 6 feet tall, appeared to weigh 150 pounds and had long, droopy face. His hair was black and curly, police said.

Anyone with information is asked to call Sgt. Linda Gibbons at 650-363-4063 or the Sheriff’s office at 800-547-2700.
