Amazon is yet to remove the 'hugely distasteful' coronavirus-themed Halloween masks from its website.The internet giant has vowed to take the product off the site after they were criticised by horrified parents.It came as UK police chiefs warned trick-or-treating and Bonfire Night may need to be cancelled due to the pandemic.The latex masks, which are being sold for as much as £28.29, resemble an illustration of the Covid-19 virus - but with big haunting eyes and jagged teeth.They are being listed on the online marketplace by a number of sellers based in China and are said to be "suitable for adults and teenagers".One seller wrote in the product description that the mask will leave an "amazing and lasting impression".
