The sun shines though the distinctively shaped leaves of marijuana plants May 24, 2005.

Two convicts on day-release from a German prison were caught tending their illegal cannabis crop in an empty warehouse nearby, German authorities said on Monday.

German customs agents discovered the 1,200 cannabis plants in the warehouse in the western town of Moers and detained the two convicts, immediately ending the furlough and sending them back to jail.

The customs agents said the men, who were on day-release to find jobs, were planning to export their harvest to the Netherlands.
