MASAKA, Uganda, June 10 (UPI) -- Police in Uganda said they are investigating the origins and purpose of a huge marijuana crop found in the garden of a convent.

Masaka district police officials said investigators discovered a marijuana plantation covering an entire acre of land in the gardens of the convent, which was not specifically identified by police, the BBC reported Thursday.


Southern regional commander Emmanuel Muhuirwe said two porters were arrested and released on bail pending charges while two nuns were questioned but not arrested.

One of the nuns was quoted as saying the marijuana was used as a health treatment for the convent's pigs and other farm animals.
