A longtime dealer will be joining his customers behind bars after posing as a visiting relative to sling illicit substances to convicts.

The 24-year-old suspect was caught by cops en route to Pursat on Wednesday, after a tip-off by an undercover agent.

When authorities accosted the devious dealer, they also confiscated an undisclosed amount of crystal meth.

The suspect awaits sentencing at the Phnom Penh Municipal Court before returning to prison sans his disguise.
