Information from the public led to the arrest of a teenager in the alleged knifepoint robbery of a bicycle from an 11-year-old boy on a school playground in Santa Clara on July 7, a police spokesman said.

The 11-year-old boy told police that at about 5:30 p.m. on July 7, he was playing at Washington Elementary School at 270 Washington St. when the male suspect approached him, Santa Clara police Lt. Kurt Clarke said.

The suspect then robbed the boy of his bicycle at knifepoint, according to police.

Officers later obtained surveillance video from a nearby 7-Eleven store that contained images of the suspect, released the video to the public Thursday and asked for help in finding him, Clarke said.

Detectives soon received many leads about the suspect’s identity and the tips led to the arrest of a 15-year-old boy from San Jose.

The minor was booked into the Santa Clara County Juvenile Hall on suspicion of robbery on Friday, according to Clarke.

The information from the public also assisted police in naming associates of the suspect who were also in the video, police said.

Officers located the 11-year-old’s bicycle and returned it to him.

The community played a key role in the arrest of the juvenile suspect, Clarke said.
