Justin Bieber's tour assistant has been handed 12 months probation after pleading guilty to two charges of attempting to import border-controlled drugs into Australia.

Terrence Reche Smalls made the plea by phone during a court hearing in Brisbane on Friday (13Jun14), and he was given a 12-month good behaviour bond.

He was told he will face a hefty fine if he breaches the deal.

Smalls was reportedly caught in possession of cannabis plant material and resin when he was stopped at an airport in Brisbane last year (Nov13), while on tour with Bieber and his entourage.

He initially claimed to have no knowledge of the drugs, but has since accepted responsibility for packing it in his luggage.

The news comes a day after Bieber learned a felony phone stealing charge against him has been passed back to the Los Angeles City Attorney after police officials failed to find evidence to take the matter further.

The singer was accused of taking a mother's cellphone after spotting her trying to take a photo of him during a visit to an amusement park in Sherman Oaks, California last month (May14).

Los Angeles police officials investigated the woman's allegations, and interviewed witnesses but no one saw the Baby singer grab her phone from her handbag - as she claimed.

As a result, District Attorney's officials have rejected felony prosecution and sent the case to the City Attorney.
