Police: Diamond heist at Shreve's an inside job

The Globe reports a former employee of the Boston branch of Shreve, Crump and Low was arrested on charges she replaced two diamonds headed to the Chestnut Hill branch with cubic-zirconia replicas.

The Chestnut Hill store noticed the swap in September.

The Suffolk County District Attorney's office reports Tanya Nichols will be arraigned on Feb. 9. She was allowed to walk out of court after a Boston Municipal Court judge denied a request from prosecutors to revoke her bail in an unrelated Lynn case.

Innocent, etc.
