Upinder Gupta and her husband Semerjit Singh spent $1,000 on surveillance cameras after their home in Fremont, CA, was sprayed with green paint balls three times this summer, according to a report in The Daily Review. Last time, the vandals scratched the length of her minivan and Singh’s Lexus, the report added.

Gupta is certain that the culprit is a neighborhood teenager who has harassed her teenage son because he wears a turban. Detective Bill Veteran, however, was quoted as saying that without an eyewitness seeing the damage being done, they can’t charge the juvenile with a crime. The paper said, quoted police, that when officers confronted the teenager and his father about vandalism that occurred on Aug. 1, they didn’t admit or deny guilt.

Gupta, a civil rights activist who is a board member of the Fremont-based Interfaith Freedom Foundation, a group that works for religious liberty, was quoted as saying that she saw the teenager and two others firing paint balls at her door and painting the windshield of their cars.

Police officer Wanda Roland assured Gupta that the father would apologize and return the next day to clean the graffiti.

They didn’t apologize or clean up the mess, and in a follow-up police report, the father of the teenager told Roland that his son was innocent, Gupta was quoted as saying.
