The man behind the door at 47 Mercer Street has a name.

Arthur Selby, age 51, of Thornhill, is the sole director of Southgate Safety Consultants Ltd, the compliance firm that existed on paper for nearly three years, occupied a single upstairs room above Canford & Sons printshop, employed no staff, conducted no inspections, earned no revenue, and allegedly produced the fire safety certificates that are now Exhibit A in the Greystone Wharf arson investigation.

The identification, confirmed by the Metropolitan Constabulary on Monday following a Companies Registry inquiry, raises more questions than it answers.

A Quiet Life

Selby is a bookkeeper. He has worked for the past four years at Loxton & Gray, a textile storage warehouse on Havelock Road in Thornhill. Before that, he spent eleven years as an accounts clerk at Whitaker & Sons, a Docklands shipping supply firm that closed in 2021.

He has no criminal record. He holds no fire safety qualifications. He has, so far as this newspaper has been able to establish, no obvious connection to the fire inspection industry.

And yet his name appears on the incorporation documents for Southgate Safety Consultants, filed on 14 March 2022 — six days after Whitaker & Sons formally ceased trading.

The Ashcroft Thread

The connection that will interest investigators is this: Whitaker & Sons, during its final years of operation, supplied rope, rigging, and marine hardware to a number of Docklands warehouse operators. Among its clients, according to commercial records reviewed by this newspaper, was Ashcroft Property Group, which purchased supplies for at least three of its waterfront properties between 2019 and the firm’s closure.

This does not prove that Selby knew Gerald Ashcroft or acted on anyone’s instruction. It proves only that Selby’s former employer did business with the company at the centre of the Greystone investigation.

Senior Inspector Callum Frye confirmed that Selby has been asked to attend a voluntary interview at Constabulary headquarters on Foundry Row. “We are making inquiries,” Frye said. “Mr Selby has been cooperative.”

The Missing Pieces

What remains unclear is how Selby came to register a compliance firm in the first place, and whether he did so at his own initiative or at someone else’s direction.

Douglas Canford, the Mercer Street landlord who rented the upstairs room to Southgate, told this newspaper last week that he saw the tenant “six or seven times in total” over three years. The room was vacated in December 2025 and contained no equipment, no files, and no inspection tools when sealed by the Constabulary.

Elise Braddock, solicitor for Vincent Drury — the Greystone Shipping director who told investigators he obtained fire certificates from Southgate — declined to comment on Selby’s identification. “My client has cooperated fully with the investigation and has nothing further to add at this time,” she said.

Solicitor Edmond Crayle, representing Gerald Ashcroft, did not respond to a request for comment.

What Comes Next

The Constabulary now has a chain that runs from the forged certificates, through Drury, to Southgate Safety Consultants, to Arthur Selby. Whether that chain extends further — and in which direction — is the question that Senior Inspector Frye and his team will be working to answer.

The Ashcroft tax demand of 2.4 million florins, issued on 21 February, reaches its fourteen-day payment deadline this week. The Docklands safety audit, meanwhile, has assessed 52 of 72 vacant properties. At least nine have shown irregularities in their fire safety documentation.

One bookkeeper. One empty room. Three forged certificates. And a fire that destroyed a warehouse in February.

The arithmetic of this case is getting smaller and more specific, which is exactly how cases get solved.
