PLEASANTON -- A high school student suspected of tagging various properties with graffiti over the past three months, causing an estimated $10,000 in damages, finally got tagged himself.

Police last week arrested a 16-year-old Vintage High student on suspicion of felony vandalism after finding evidence of the vandalism while serving a search warrant at his residence, Pleasanton police Sgt. Kurt Schlessinger said.

The student was taken to Alameda County Juvenile Hall. He was not identified

The graffiti tags, marked by the letters "SCOS", began in December and continued through February, Schlessinger said. Most of the graffiti was found on property belonging to the city, but some private residences and businesses also were hit, Schlessinger said.

"We asked him what the letters meant, and he said that he just liked the way they looked," Schlessinger said.

Police worked with the Pleasanton Unified School District to identify the student as a suspect, and after the search warrant was served and evidence found, he admitted to involvement in all the cases that were being reported, as well as many others, Schlessinger said.

In all, the student was linked to 42 incidents of vandalism and police estimated that he has caused more than $10,000 in damage to city property, Schlessinger said.

Police also emphasized that the arrest was not related to a graffiti threat found at Foothill High School that has increased the police presence on the campus this week.

"I wish it was," Schlessinger said. "But that's a completely separate issue. That investigation is ongoing."
