Which Dragon's Den investor bought the retail chain Robert Dyas in 2012?

Theo Paphitis bought the retail chain Robert Dyas in 2012.

Robert Dyas is a British retailer selling household goods, hardware, kitchen products, and related items. Paphitis's acquisition placed the chain within the portfolio of a businessman already known for developing high-street retail brands.

The purchase is a useful example of Paphitis's business background outside television. On Dragon's Den, he often evaluated pitches through a retailer's perspective, considering product appeal, pricing, distribution, and whether a company could work in physical shops as well as online.

Robert Dyas is separate from Ryman, another retailer associated with Paphitis. Ryman focuses mainly on stationery and office supplies, while Robert Dyas has a broader household and hardware range. Both names can therefore appear in accounts of Paphitis's career, but the 2012 acquisition in this question refers specifically to Robert Dyas.
