A sacked army general linked to a cocaine smuggling ring is under house arrest while authorities debate how he will be tried, a government spokesman said Monday.

Gen. Gustavo Arriazola and four other accused lower-ranking army officers could face up to 20 years in prison if convicted under a tough new civilian anti-narcotics law, Information Minister Herman Antelo said.Arriazola is under house arrest at his home in Cochabamba, 160 miles southeast of La Paz, Antelo told United Press International.

As commander of the 7th army division in Cochabamba, Arriazola had jurisdiction over Bolivia's prime cocaine-producing Chapare region before his sudden firing last week.
