Los Angeles ( CNN ) -- Justin Bieber is completely off the hook for an incident in which a Los Angeles woman accused him of trying to take her cell phone last month . But a Los Angeles prosecutor is expected to soon charge Bieber , 20 , with vandalism in a separate incident , the egging of his neighbor 's mansion , a source involved in the case told CNN on Monday . The Los Angeles city attorney decided Monday there was `` a lack of evidence '' to prosecute the singer for attempted robbery in connection with an argument with a woman at a miniature golf park last month , according to spokesman Rob Wilcox . The case was handed to the city attorney 's office last week for consideration of a misdemeanor charge after the Los Angeles district attorney declined to file a felony charge . Justin Bieber avoids felony robbery charge in cell phone 'tussle ' A criminal charge in the egging probe is coming as soon as Monday afternoon , a source told CNN . The Los Angeles County district attorney has been considering the case since February , when sheriff 's investigators recommended that Bieber , be charged with felony vandalism for the January incident . The vandalism case is what lawyers call a `` wobbler , '' meaning the district attorney must decide if it will be prosecuted as a felony -- which could have much more serious consequences for the singer -- or as a misdemeanor . There was no indication which charge would be filed against Bieber , the source said . Justin Bieber : 'Do n't believe rumors ' A spokeswoman for the district attorney declined to confirm the report . `` When something happens , we will let everyone know at the same time , '' Jane Robison told CNN on Monday . The family living in the mansion next to Bieber 's in an exclusive Calabasas , California , neighborhood accused the singer of tossing eggs from his yard onto their home . Los Angeles County Sheriff 's Department detectives are pushing for a felony charge , based on the estimated $ 20,000 in damage caused by the eggs . Is Justin Bieber getting special treatment ? Bieber 's attorneys met with prosecutors in March to argue that since the egging was `` a silly prank '' and Bieber has no criminal record , it should be treated as a misdemeanor , two sources at the time said . Bieber , 20 , has since moved from the neighborhood , selling the mansion to Khloe Kardashian . Bieber 's drunken driving charge in Miami is also still pending , although a source close to that case said talks are under way to reach a plea deal to avoid a trial . Justin Bieber again caught in racial controversy .
