The consortium includes two former senior figures from House of Fraser – John King, who was the company’s CEO, and Stefan Cassar, the store group’s ex-chief financial officer.
Raging Bull was launched in 2007 by ex-England international Phil Vickery.
Primarily sold through department stores and online, the rugby heritage brand, whose size offering goes up to 6XL, has been particularly successful in the ‘big and tall’ sector.
It has also recently launched women’s and boy’s range.
King says: “We first came across the brand in 2010 and were impressed with the product and the way the company was run.
“There is an emphasis on integrity and teamwork, which comes ultimately from Phil and his sporting values.
“We see huge potential not only in the UK, but in overseas territories where rugby is popular.”
Raging Bull currently has a turnover of around £5 million.
The company says the investment will help it continue the expansion of its team, develop its product ranges and spend more money on marketing activities.
Vickery, who will continue his involvement in the company, says: “When I started the business, I saw the opportunity to create a clothing brand that represented what I had learnt through my sporting career – that is to be strongly competitive, but with teamwork and respect.
“John and Stefan recognise these values in the brand and with their retail experience will help us take the business forward in the UK and internationally.”
