The Los Angeles County district attorney filed charges in August against a former Santa Clarita assistant city engineer who allegedly redirected to his own account more than a half-million dollars in refunds of cash payments in lieu of bonds from contractors, engineers and others that performed services for the city.

David Rubira was originally arrested in May but many details of his alleged crimes had not previously been disclosed. City of Santa Clarita officials say they will seek restitution as well as making a claim under an employee-fraud insurance policy with a $1 million limit.
