British couple called cops and said they have grown a huge marijuana bush...

How that could happen?  - Easy!

Elderly couple went to shop on one of the local garage sales and bought a nice plant that later they put in there back yard of their house in Bedforth and were taking good care of the plant watering and pottering it till one of the neighbors pointed out that the plant might be illegal. 

So, the couple called cops on themself. When the police arrived they found Cannabis Plant, the size of it was so big that the police officials said its the biggest marijuana plant they have ever confiscated.

 British couple wasn't  charged with marijuana possession. At the same time who was the seller of the plant and how much they paid for it wasn't announced.
