Officers carried out searches at six addresses and recovered a quantity of drugs believed to be class A drugs.
Today’s arrests brings the total number of those arrested over the three days of action in Bridgend and the Vale of Glamorgan to 37 people.
Detective Inspector Dean Taylor said: “Today around 45 officers took part in the third day of action known as Operation Avalanche. This is a large-scale operation to tackle the drug supply in Bridgend and the Vale of Glamorgan.
“Today’s operation was focused on Bridgend – two of the people in custody were arrested in the town centre. We know the community have been concerned about drugs in the town centre and we hope today’s enforcement highlights our tough approach to tackling these issues.
“Drugs have no place in our communities and we hope Operation Avalanche will serve as a warning to others involved in illegal drug activity that their actions will not be tolerated.
“If you have any information on drug dealing then please let us know so we can act.”
