After stockbroker Rayhan Qadir tweeted this...
...it's fair to say significant parties took quite an interest.
He then claimed it was all a "bad joke". But now his employer, Hargreaves Lansdowne, has told The Telegraph:
One of our employees has failed to conduct themselves to the standards we expect of our staff. We find these online comments totally unacceptable. Upon becoming aware of this issue we have terminated this person's employment with immediate effect.
And Avon and Somerset police have confirmed to the paper that they're investigating the tweet.
Twitter is divided on whether this was a reasonable course of action.
