The tweet, which was sent at around 5am on Tuesday (July 10), says: "Last night we attended a job that we'll never forget. Really proud of how the team dealt with it and really important that we sat down together afterwards to debrief.

"Thanks to colleagues over at @Humberbeat as well."

The Yorkshire Evening Post has asked both West Yorkshire Police and Humberside Police to clarify the tweet, however both have refused to do so.

Humberside Police said it was "not something we're able to speak about for operational reasons".
