Bank commercial director Carl Brewins has departed the young fashion retailer.
Brewins, who joined the young fashion on a contract in November, is planning to explore opportunities outside of the fashion industry.
It is not known if Bank will replace Brewins, one of the co-founders of young fashion chain Republic.
Bank owner JD Sports Fashion has struggled in the past year, with operating losses before exceptional items rising to £6.4m for the 12 months to February 1 compared with a £1.7m loss the year before. It said a “disappointing” performance at Bank hampered the fashion division.
Bank was unavailable for comment.
