Second 'unexploded device' found at RAF Waddington
A second "unexploded device" has been discovered at an RAF base in Lincolnshire, officials have said.
The device was discovered by contractors working on runway improvements at RAF Waddington, near Lincoln.
Last week, workers discovered another device, which turned out to be a World War Two practice shell.
The A15 between Lincoln and Sleaford was closed while the second device was assessed.
More than £35m is being spent rebuilding and lengthening the runway at the base.
