The suspect is wanted in Belgium, where he was sentenced to 40 months in prison.
Spanish news outlet EFE said that the suspect had been sentenced to 40 months in prison and a fine of €16,000 in Belgium.
EFE added that the police arrested the suspect while he was trying to flee to Morocco through the international port of Almeria.
At the port, the suspect had to show his documentation at passport control. Customs services then discovered that the suspect is the subject of an extradition order from a Belgian court issued on January 16, 2016.
EFE said that the suspect sold more than € 730 000 of drugs between October 2016 and March 2017. The news outlet said that the suspect confessed that he was selling cocaine and heroin.
EFE added that police in Almeria and El Ejido detained ten suspects with European arrest warrants.
The suspects were from Romania, Belgium, Morocco, France, UK, and Russia.
The suspects were involved in several crimes including fraud, tax evasion, social security fraud, drug trafficking, irregular migration, and sex crimes.
Moroccan and Spanish security services regularly collaborate on the fight against drug trafficking, irregular migration networks, and counterterrorism.
