RollOnFriday can reveal that it is not just Allen & Overy's Belfast office that has been suffering poo issues: Herbert Smith has also been visited by a phantom shitter.

The dirty protest is not quite as gross as the one at A&O. The perpetrator apparently left his or her leavings on the floor of the womens' toilets rather than in the soap dispensers. But it happened repeatedly, and resulted in the supremely tactful HR team asking staff whether anyone had been feeling unwell.

Since the matter was raised at the start of the year the incidents have now ceased. A spokesman for Herbies pointed out that the building was shared with another company, and that builders had been on site at the time of the incident, so the culprit may not have been at the firm.

Or, of course, they might have been, and have since moved to A&O where they've raised their game. Maybe they're on some awful pilgrimage round the Belfast outposts of City firms and will crop up elsewhere next week. Watch this space.
