"I am very pleased to welcome Daniel Kretinsky, Pavel Horsky and 1890s holdings a.s to West Ham," Brady said.
"We are always looking to continue to progress and Daniel's involvement brings investment which strengthens the club's position and in turn will assist in the development of the club's key area of focus.
