Facebook has delayed the launch of its new dating feature in Europe, after a last-minute visit by officers from the Irish Data Protection Commission (DPC).
The DPC said it had been told about the feature just 10 days ahead of the planned launch and "no information or documentation was provided to us".
"We were very concerned that this was the first that we'd heard," it said.
Officers had gathered documents during Monday's inspection of Facebook's EU headquarters, in Dublin, the DPC said.
