Marwa, who was picked as an assistant referee in the Russia 2018 World Cup, was caught on camera receiving Sh60,000 ($600) from a reporter posing as a Ghanaian club official.
He was part of an undercover investigation by Ghanaian journalist Anas Aremeyaw Anas who filmed more than 100 African football officials accepting cash in apparent violation of the rules of the sport.
Marwa has reportedly denied any wrongdoing even though FIFA said that he would not now be going to the World Cup.
The 41-year old was among a host of four other referees picked from Africa to officiate in the sporting event slated for June 14-July 15.
He served as a FIFA referee from 2011, and was named as a reserve official at the 2014 FIFA World Cup in Brazil.
Neither Marwa nor Kenya's Ministry of Sports is yet to comment on the matter.
