A British mall that scanned shoppers using facial-recognition cameras said on Friday it is no longer using technology that advocacy groups called a threat to privacy.

Meadowhall in the northern city of Sheffield, which attracts more than 25 million visitors a year, used the surveillance with police in 2018, according to its owners British Land.

"We conducted a short trial at Meadowhall, in conjunction with the police, and all data was deleted immediately after the trial," said spokeswoman Claire Scicluna.
