Jake Livermore was involved in a bust-up with fans after being substituted against West Ham
West Ham have identified the supporter who was confronted by West Brom midfielder Jake Livermore during Tuesday's Premier League match.
The England international was involved in an angry confrontation with a West Ham fan after being substituted in the 64th minute of the 2-1 defeat and was then escorted down the tunnel.
The fan is alleged to have shouted to Livermore, and an investigation is under way to establish whether he directed abuse about Livermore's baby son, who died in 2014.
West Ham, who ejected the fan, have said they are looking into the allegations and will work with West Brom if any further action is required.
West Brom have since sent their observations of the incident to the Football Association.

Livermore was also targeted with taunts about his use of cocaine during the match last night at the London Stadium. The player tested positive for the drug in the months after his son's death.
The Metropolitan Police have said they are continuing their own enquiries, despite receiving no formal complaint, and are speaking to both clubs.
In a statement, West Brom said: "West Bromwich Albion would like to clarify an incident involving our player Jake Livermore in last night's Premier League game at West Ham.
"Following his substitution in the second half, Jake was subjected to general abuse from home supporters which he shrugged off. However, he acknowledges that he moved to confront one spectator who chose to make a comment about the death of his infant son.

"The club would like to think that all right-minded football supporters could understand this reaction which did not result in any physical exchanges before Jake was led away to our dressing room.
"Jake is an outstanding young individual who has the total support of everyone at the club and he has made it clear he considers this statement to be an end to an unhappy incident.
"Albion were very appreciative of the swift response by the officials of West Ham in dealing with this matter and are more than happy to leave any further action they deem appropriate in their hands.
"The club has responded to an FA request to offer our observations of the incident and will not be making any further comment."
