NATICK, MA — The Natick Mall was the site of an attempted robbery Tuesday when a man tried to make off with a woman’s high-priced diamond.

Kathleen Sanfacon had agreed to meet a potential buyer of her gemstone near a bank branch inside the mall, WCVB-TV 5 reported.

When Keyjuan Webb arrived, he examined the heart-shaped stone and said he’d pay $27,000 for it. But then he bolted, taking the diamond with him.

Sanfacon grabbed Webb, who dragged her as he tried to flee and threatened to shoot her, the report said.

He was eventually subdued with help from bank employees.

Webb, 23, of Beverly, was arrested at the scene and then arraigned on Wednesday.
