Twenty people arrested by gardaí in the past 48 hours as part of a crackdown on the sale and supply of heroin and crack cocaine in the Dublin region are due in court this afternoon.
Some 45 people were arrested in the Garda operation, which involved drug units from Kevin Street, Pearse Street and Store Street stations.
Some 150 charges are being brought as a result of the operation.
The arrests follow a six-month covert operation in which gardaí and the Garda National Drug Unit have gathered evidence against those who they describe as "significant targets", all of whom are expected to face multiple charges.
The 20 are due before Dublin District Court.
