The National Narcotics Agency on Tuesday confirmed three crew of an Indonesian budget airline were among four people detained in a drug-linked raid.

News broadcasts on local television quoted the agency head, Budi Waseso as saying the suspects were picked up while having a drug party at an apartment in Wilayah Tengerang near here Monday.

He said the suspects, aged between 20 and 34 comprised a co-pilot, a male and female flight attendant and a housewife, who is a friend of one of the crew.

"When we searched for evidence, there was none but our focus was to dismantle the drug network," he told a press conference.
