Wellington - Text messaging may have some advantages, but a New Zealand drug dealer has found that it can be very bad for business when you don't know where the recipient is.

When Anthony Crown texted a methamphetamine offer he didn't know his client was sitting in a Wellington police station having just been arrested for burglary.

Police replied to the text and arranged a drop-off point where Crown was arrested.

A check of his cellphone log showed three other drug offers made by text messaging and even while in a police cell his cellphone was receiving messages from potential buyers.

Crown was jailed on Friday for two years and three months on various drugs charges.
