The 23 year-old forward's brother and father have decided not to travel with the player to the European Championships due to concerns they may be victims of abuse
The England international's brother voiced his and Walcott's father, Don's decision via social networking site Twitter, stating that they had chosen to stay at home for safety reasons.
"Unfortunately my dad [and] I have taken the decision not to travel to the Ukraine because of the fear of possible racist attacks/confrontations," he wrote.
Racism is known to be a problem in eastern Europe and the Foreign Office makes explicit reference to such in their official travel advice for the area ahead of this summer's major championships.
"Although the vast majority of visitors experience no difficulties, foreign nationals have been the victims of violent crime in Kiev and other major cities,” the FCO website warns.
"In some cases attacks have been racially motivated.
"Travellers of Asian or Afro-Caribbean descent and individuals belonging to religious minorities should take extra care."
Walcott was one of eight black players named in Roy Hodgson's 23-man squad for the tournament and it is believed that no other player's family has yet raised any concerns that they may have with the FA.
