Los Angeles police released surveillance video after a man and a woman were attacked in two separate incidents on Monday.
In the first incident, a man standing by a bus stop near Florence Avenue and Avalon Boulevard was slashed in the face by an edged weapon at about 8:40 a.m.
About 15 minutes later, the suspect slashed a woman near 59th Place and Avalon Boulevard, causing severe injury to her face and ear.
Both victims are expected to survive.
"He's striking from the rear, and when you do that, he is cutting all of these people really deep. It's hard to say if it's a knife, possibly a box cutter," said LAPD Detective Steve Garcia.
Police say the serial slasher is accused of attacking eight men and women in 11 days. Two of the victims were slashed in the South Gate and Lynwood areas.
The suspect strikes in broad daylight, police say. The victims range in age from 20 to 85 years old. One victim is seen on video going into a bakery in South Gate, asking for help after being slashed in the face.
"In one incident in Harbor Division, it appears he tried to take a purse. The victim fought back, the suspect rode off laughing," Garcia explained.
The suspect is described as between 18 and 30 years of age with short hair. He's about 5 feet 6 inches to 5 feet 8 inches tall and weighs about 150 pounds. He's usually seen riding a black and green mountain bike.
Detectives are asking the public to be cautious and are hoping for their help in providing any information that would lead to the identification of the suspect. Anyone with information is urged to call Detective Corral or Detective Garcia, Newton Area Detectives, at (323) 318-3610 or (323) 846-6562.
