NINE people have been apprehended for alleged illegal cockling in Gower.
It follows an investigation involving Environment Agency Wales and South Wales Police.
The area under scrutiny was Burry Inlet, near Llanrhidian.
During the investigation, Environment Agency Wales alleged nine local people were found in possession of cockles taken from the beds illegally. They have now been reported for fisheries offences and face possible legal action.
More than four tonnes of cockles were seized but could not be returned to the cockle beds due to the tide.
Lyn Richards, of Environment Agency Wales said illegal activity threatened the livelihood of licensed cocklers and could be incredibly dangerous to those unfamiliar with the tides. "We strongly advise people not to try and take cockles illegally as they put themselves at risk of harm and of being prosecuted," he said.
