A 43-year-old homeless man suffered non-life-threatening injuries when he was stabbed four times early Thursday morning while sleeping on a street in the Lincoln Park area, police said.

The stabbing happened shortly before 1:20 a.m. on Willie James Jones Avenue, just north of Imperial Avenue, San Diego Police Officer Robert Heims said.

The victim was sleeping near a wall when he was awakened by a man stabbing him three times in the side and once in the right rib area, Heims said.

Paramedics took the victim to a hospital for treatment of his injuries, which were not believed to be life-threatening, the officer said.

The suspect was described as a thin man with a ponytail who was last seen wearing a red, white and blue jumpsuit.

Authorities have not disclosed a suspected motive for the stabbing.
