Guardia Civil’s organised crime unit mounted a anti-drugs operation in Palma.
A series of raids were mounted simultaneously with a number of drugs swoops carried out across Spain as part of a nationwide operation.
Yesterday morning, armed officers wearing ski masks and with air support from a Guardia Civil helicopter stormed at least two properties in the Son Gotleu neighbourhood of the capital.
The operation was still ongoing last night but at least 13 people had been arrested.
Police sources also confirmed that over eight kilos of various drugs have been seized over the past two weeks since the operation was first given the all clear by police chiefs.
It was also revealed last night that further arrests may be made .
Police are not ruling out another wave of raids on suspect properties in Palma.
