It was in July that the man got caught when he got off a bus at E4 in Haparanda.
It all started with the customs narcotics dog showing interest in the man and after that the officials decided to check him.
1,000 narcotic tablets were found in a paper bag.
The man is now sentenced to prison for two years and eight months for serious drug offences.
The district court writes that the act must be assessed as serious because it involves a large amount of narcotics.
The man has admitted in questioning that he had the tablets, but believes that he lacked intent as he did not know that they were narcotics.
