A Devon pensioner discovered she was unwittingly growing a 5ft (1.5m) tall cannabis plant from a pack of bird seeds - after phoning a BBC Radio Devon phone-in programme.

Patricia Hewitson, from Exmouth, contacted the station's Sunday gardening programme asking for help identifying "a weed".

After discovering it was an illegal cannabis plant the police were involved.

Officers said Mrs Hewitson was growing the plant illegally but in good faith.

Mrs Hewitson said: "I sent a picture in via email and I got a couple of interesting emails back, including one from the police.

"They said they wouldn't prosecute me as I'd done it in good faith."
