LONDON -- British police say an elderly couple unwittingly grew a monstrous cannabis plant in their yard after buying what they thought was an innocuous green bush at a flea market.
Police in Bedford, a commuter town 90 kilometers (55 miles) from central London, posted a picture of a luxuriant cannabis plant growing as tall as the fence in what appeared to be someone's back yard.
In a message posted to Twitter Friday the force said the plant had been "seized today."
"Elderly couple bought shrub at car boot sale, tended carefully-biggest cannabis plant we had seen!!" the message exclaimed.
Further details about the couple – or how either it or police got wise to the plant's true nature – weren't immediately available late Monday.
