Justin Bieber and his entourage were detained at the Brisbane, Australia airport while customs agents looked for drugs … and TMZ has learned they allegedly found weed on one of Justin’s pals.
The Australian Federal Police tell us … a 19-year-old man was detained back on Nov. 24 … but was released after getting a stern warning for using “inappropriate language.” He reportedly swore at the officers.
Sources connected with the incident tell us Justin was the one with the potty mouth.
The AFP says a security check turned up an unknown amount of pot on a 23-year-old man in Justin’s entourage. The suspect was released, but got a ticket for allegedly importing drugs.
Sources close to Justin tell us the suspect had a disposable vaporizer — basically an electronic device to smoke marijuana — which had residue in it.
We’re told an attorney for the suspect appeared in court today, and paid the fine.
It’s been one helluva tour — as we first told you … one of JB’s bodyguards was arrested last month in Hawaii after allegedly attacking a photographer on the beach — and was also caught on video attacking a photog in Sydney.
Maybe Bieber is more rock ‘n’ roll than we thought.
