Police are appealing for information after 52 copper anodes stored in cyanide soaked cotton bags were stolen.
And while the risk of harm is generally considered to be low, detectives investigating the theft say the rods or canvas bags could be potentially harmful if any possible trace of cyanide is inhaled or if a person touches them and their hands then make contact with their mouth.
The rods, each weighing 30kg, measuring 1 metre long and 8cm across, were stolen during a burglary at an industrial premises on Vickers Industrial Estate, Morecambe overnight on March 30.
DC Dylan Hrynkow said: “We believe this was professional job as the rods were put through rinsing tank before they were taken, reducing the risk of harm to those handling them.
“We are urging anyone who may have any information about the location of these anodes to get in contact with us as soon as possible.
“If you have been offered these items for sale, please do make contact with us. Similarly, if you are wanting to hand these in, please call us prior to doing so.”
Similar advice was issued by police last month after 200 cyanide coated metal balls were stolen at from industrial premises on Poulton Industrial Estate.
Anybody with any information should contact 101 quoting incident reference 0140.
