The game was marred by a string of controversial incidents, refereeing decisions and alternations.
Jamie Vardy was sent off for diving and was one of a number of Foxes stars to be caught on camera verbally abusing ref Jon Moss.
Robert Huth was his usual aggressive self and Leicester's fans didn't win any new friends with constant appeals for every decision grating on neutrals.
The Foxes have also launched an investigation after Hammers owners David Gold and David Sullivan and their families were forced out of their seats by vitriolic abuse from some Leicester fans.
Sullivan described it as the worst abuse he has suffered in years and a "throwback to the bad old days" - as reported by The Mirror.
Champions League hopes hampered
The result hampered the Hammers' hopes of a Champions League spot even if Wednesday night's 3-1 win over Watford kept those faint ambitions alive.
While there is no love lost between the Hammers and Spurs in recent years, the manner of the North Londoners' win over Stoke City has met with begrudging praise even from the most ardent of West Ham fans.
Goodwill towards Foxes dissipating?
Many fans on social media have been highly critical of the Foxes and it appears much of the goodwill from neutrals over their fairytale title tilt has dissipated somewhat since their match with the Hammers.
West Ham showed how professional they were when they went for the jugular against Leicester and were a credit to the Premier League.
Hammers fans are a knowledgeable bunch and know good football when they see it.
Could it be they have made peace with the prospect of their rivals winning a first title in decades, especially as it gives them hope for their own future ambitions of a loftier existence.
Or does the tribal hatred run too deep?
