BALI, Indonesia -- Indonesia prosecutors are seeking a 15-year prison sentence for a British woman accused of smuggling cocaine worth $2.5 million into the resort island of Bali.

Prosecutor Lie Putra Setiawan told the Denpasar District Court on Thursday that Lindsay June Sandiford, 56, was guilty of violating the country's strict narcotics law.

Sandiford was arrested in May when customs officers at Bali's airport discovered 3.8 kilograms (8.4 pounds) of cocaine in her luggage.

Another Briton, Rachel Dougall, was sentenced to one year in prison in a separate trial Thursday for failing to report a crime to authorities, and a third, Paul Beales, got 4 years imprisonment on Wednesday for illegal possessing of 3.1 grams of hash.

Indonesia has extremely strict drug laws and convicted smugglers are often executed.
