The attack happened at a bus stop near Manchester and Normandie avenues around 1 a.m. The woman was reportedly beaten and stabbed. She was taken to the hospital where she was listed in critical condition.
Upon arrival, a Los Angeles police supervisor saw the suspect assaulting the woman and the suspect fled from the bus stop on foot. A perimeter was established and canine units were able to find the suspect just north of the crime scene.
Police believe the suspect could be a serial rapist responsible for three assaults that occurred in the South Los Angeles-area over the weekend. They happened within a 2-mile radius and at night.
Manchester Avenue was closed off for two blocks at Normandie Avenue as authorities gathered evidence. Police said they were confident they had the right man responsible for all four incidents.
"We've had resources out here and ultimately we believe that we have the suspect responsible for those [attacks] in custody," said Los Angeles Police Capt. William Hayes.
The suspect could face an attempted murder charge.
Police notified local residents that they would continue to monitor and patrol the area.
Anyone with information was asked to call the Los Angeles Police Robbery-Homicide Division at (213) 486-6910.
