Indonesian customs officials have arrested two foreigners accused of attempting to smuggle drugs onto the tourist island of Bali.

Customs chief Himawan Indarjono said Thursday that British citizen Adam Scott and German Siegfried Karl Achim Ruckel were arrested at Bali's Ngurah Rai airport.

He said officers seized a bottle with 655 Diazepam tablets, also known as Valium, from Scott, a computer analyst who arrived from Bangkok on Jan. 24. The amount was judged to be more than he needed for personal use.

Another customs official, Husni Syaiful, said Ruckel arrived two days later from Doha and possessed 7 grams (0.25 ounces) of heroin, 0.2 grams (0.01 ounces) of amphetamine and 15.3 grams (0.54 ounces) of morphine.

Indonesia has tough anti-drug laws. Traffickers can receive the death penalty.
