A cannabis plantation has been discovered close to one of the venues which hosted the London 2012 Olympic Games.

Hertfordshire Police officers found the crop of mature plants during routine patrols at woodland in Lee Valley Park in Waltham Cross on Tuesday.

The white water centre close to Trinity Lane, where the 20 plants were found, was used for the canoe slalom events.

Police are appealing for information and witnesses.

Lee Valley Park said it was liaising with the force to confirm the exact location where the plants were found at the 10,000-acre (4,047-hectare) park.
