Wild beavers 'destroying flood defences' in Tayside

Wild beavers became extinct in Scotland sometime during the 18th century as a result of over-hunting, but the rodent has recently been spotted in several Perthshire rivers.

The Scottish government is now considering what to do about them.

BBC Scotland Correspondent James Cook reports from Tayside.
