Justin Bieber cleared in Los Angeles attempted robbery case

Justin Bieber has been cleared of wrongdoing in an attempted robbery investigation in which the Canadian pop star was accused of trying to take a woman's mobile phone, the Los Angeles City Attorney's Office said.

Prosecutors rejected the allegations because of insufficient evidence to back up the claims, City Attorney spokesman Frank Mateljan said on Monday.

Bieber, 20, was accused in May of trying to take the woman's mobile phone after she was suspected of taking photos of him at an amusement park in Van Nuys, California, in Los Angeles' San Fernando Valley.

Representatives for Bieber did not immediately respond to a request for comment.

The Boyfriend singer has had a string of recent legal issues, including an assault charge in Toronto and charges of driving under the influence, resisting arrest and using an expired license in Miami Beach, Florida.

Bieber is also under investigation for allegedly pelting a neighbour's home in nearby Calabasas, California, with eggs and causing damage.
