TWENTY-NINE people have been arrested in three Spanish cities as police broke up an international gang trafficking in heroin.
Officers found a laboratory in Pontevedra where a high-grade of the drug was adulterated with other substances before being sold on the streets.
They also seized €35,000, a handgun, 11 high-value vehicles and documentation relating to the transportation of the drugs.
The heroin had largely come from the Balkans, Turkey and the Netherlands.
It is thought the gang were behind the entire supply of the drug to the province of Galicia.
Officers from the Guardia Civil took part in the investigations and the raids on premises in Pontevedra, Madrid and Ourense.
Among those arrested was a Spaniard who will be transferred to prison to serve a 14-year sentence and a Madrid-based doctor suspected of hiding the drugs when they arrived in Spain.
