This is another leak. Some or all autonomous communities in Spain have their own police (similar to state police in the US), with Catalan police being one of the largest.

This leak reminds me of the time a Russian group launched a bot campaign to destabilize Spain and support Catalan independence, with enough success to be called out by the Spanish defence minister [1]
