Man grows pot in jail, says they're tomatoes

A British prisoner convinced guards his marijuana plants were tomato plants -- and they even allowed him to decorate one as a Christmas tree, a source said.

Mohamed Jalloh, 28, of Brent, North London, grew his pot plants at Verne Prison in Portland, Dorset, in southern England, and for five months, guards admired his gardening, The Sun reported Saturday.

But after another inmate told guards what the plants really were, they checked out photos of marijuana plants on the Internet, and the jig was up.
