David Gold says the behaviour of some Leicester fans on Sunday was "unacceptable' after he, David Sullivan and family were verbally abused by a section of the home support .
Gold's fellow co-chairman Sullivan and his family were forced to leave their seats before the end of West Ham's 2-2 draw after also being targeted.
Sky Sports News HQ understands the abuse from a certain section of the Leicester support started when Aaron Cresswell scored in the 86th minute to put the Hammers 2-1 in front in the Premier League clash.
After the atmosphere became hostile and threatening, Sullivan, his partner and two sons were forced to leave their seats and watch the remainder of the match from inside the King Power.
"I want Leicester to win the PL and I am pleased for their fans but their behaviour towards us was unacceptable. dg," Gold tweeted from his Twitter account on Tuesday.
Sullivan and his family, who were unable to applaud West Ham off the pitch at the end of the game, needed to be escorted to their cars by security following the final whistle.
