DUBLIN, April 17 (Xinhua) -- Six suspected drug dealers were arrested in a series of operations conducted by Irish police in the country's capital Dublin, reported local media RTE on Tuesday.

A total of 250,000 euros (310,000 U.S. dollars) of suspected drug money was also seized in the operations which were carried out by the drugs and organized crime bureau of the police department, said the report.

The six nabbed include five men aged between 27 and 31 and a 24-year-old woman, said police, adding that some of them have recently returned from Australia.

Police believed that they were involved in the supply of cocaine from Europe to Australia and New Zealand, which is operated by a notorious gang group based in Ireland.

The drugs they sold in Australia were mainly targeting the young Irish living there, said police.

Police said that they are working closely with the Australian police and a number of arrests have also been made in Australia in the past few weeks in addition to a seizure of large sums of money. (1 euro=1.237 U.S. dollars)
