A shop in Los Angeles owned by Kim Kardashian and her sisters has been targeted by vandals, who tried to firebomb it.

A lone attacker hurled a Molotov cocktail at the Dash boutique in West Hollywood, which opened 10 years ago, but it failed to ignite.

Kim, Khloe and Kourtney Kardashian are joint owners of the store, which last year began offering personal styling.

Lieutenant Edward Ramirez said a witness saw a man throw a flaming object through the front window of the store on Melrose Boulevard after closing time on Monday.

He said the boutique did not catch fire and there was no damage to any property inside.

Investigators said the object hurled through the window was heavy and wrapped in cloth.
