In the most recent incident, a 16-year-old girl says he approached her on her way home from school and tried to grab her.
"She was fine initially, but immediately after that she realized that she had to fight back to get away and she did," said Lt. David Reynoso, Baldwin Park Police Dept.
Police say that the girl stabbed the man in the face with a ball-point pen, and the suspect ran off.
After hearing a description of the attacker the Baldwin Park Police linked him to two other botched kidnapping attempts.
Investigators say that the same man grabbed a 12-year-old girl last month, but she escaped after biting him on his arm.
"I didn't even see him. He just came and grabbed my arm and pulled me back," said Violet Prado, attacked by suspect.
Earlier this month police say that a suspect followed a 12-year-old boy to his home. The suspect rang the bell, but the boy refused to answer.
Investigators have warned local schools about the attacks. Students say that they are on edge.
"It makes me feel like I cannot walk in the streets. I cannot go anywhere without watching my back," said Monica Bolle, a concerned student.
The suspect is described as a Hispanic man in his 40s. He is about 5'8" with a medium build. He is balding with short hair on the sides. Investigators say that if children are approached they have to make a scene.
"It's alarming because the suspect is preying on children who are vulnerable. We tell children if they are confronted in a similar situation to do whatever they can to bring attention to themselves. and to the incident. They should kick, scream and scratch," said Lt. Reynoso.
Anyone with information on the suspect is asked to call Baldwin Park Police at 626-960-1955.
