Up to 100 swans are believed to have been killed by lead-poisoning
An investigation into the way the beautiful water birds died gruesomely from lead poisoning is pointing the finger at a determined and cunning killer pretending to be a harmless duck-feeder.
Most of the birds rescued after being targeted along a stretch of the River Wear in Chester-le-Street, County Durham, never recovered from the high levels of lead in their bodies.
The fact that x-rays did not show any lumps of the toxic metal in the birds' digestive tract has led experts to fear that the killer had gone to extraordinary lengths to wipe out huge number of water birds.
