During a major anti-terror police operation in Brussels on Sunday night, authorities asked the public to not report officers’ movements online.
For the most part, people complied and urged others to do the same.
But then a few Twitter users began posting pictures and videos of cats, to make sure that any leaking of operational details were drowned out.

The trend soon caught on, with cat memes featuring the #brusselslockdown hashtag going viral.
Afterwards police thanks the public “for taking into account the needs of the ongoing operation”, confirming they arrested 16 people.
