West Ham United co-chairmen David Gold and David Sullivan have revealed that they were the subject of abuse from Leicester City supporters during Sunday's 2-2 draw at the King Power Stadium.
The duo have informed Leicester of what happened towards the end of the contest, in which Premier League leaders Leicester salvaged a point in stoppage time from the penalty spot.
Gold wrote on Twitter: "Elderly Leicester fans turned into monsters when WHU went 2-1 up then returned to nice old people when LCFC equalised.
"I want Leicester to win the PL and I am pleased for their fans but their behaviour towards us was unacceptable."
Sullivan added in The Mirror: "We didn't stay to applaud our own players off as we felt threatened. We've spoken to Leicester and they've told us they would look into it."
Sixth-placed West Ham have drawn four league games in a row to drop seven points behind the top four.
