Police are investigating Justin Bieber over allegations he tried to steal a mobile phone from a woman he thought had taken pictures of him with it, a newspaper says.
The incident happened on Monday at a miniature golf course in the San Fernando Valley area, the Los Angeles Times reported late on Tuesday.
"He has been accused of attempted robbery," Officer Rosario Herrera told the Times.
She added that authorities have not yet talked to the Canadian pop star.
The paper said Bieber is not accused of keeping the phone.
It is the latest in a series of run-ins with the law for the 20-year-old entertainer.
He is due to stand trial on July 7 in Miami for allegedly driving while under the influence of drugs.
Bieber has pleaded not guilty to driving under the influence of substances, resisting arrest and driving with an expired licence after being arrested in Miami Beach on January 23 for taking part in an illegal street race in his Lamborghini.
Police said he had smoked marijuana and taken Xanax tranquilisers.
He has a hearing pending in Canada into accusations he assaulted a limousine driver last year, and was investigated in Los Angeles for allegedly throwing eggs at a neighbour's house.
