Four different biscuit and breakfast bar products featuring the images of police pup Chase and pals were affected by the issue, according to a recall notice published by the supermarket chain.

It said a URL which previously pointed to the supplier’s website “has been compromised and is being directed to a site that is not suitable for child consumption”.

“We recommend that customers refrain from visiting the URL and return this product to the nearest store where a full refund will be given,” Lidl added.

According to TechCrunch, the web address leads to a Chinese-language website with “numerous ads containing animated explicit and pornographic images”.
