​West Brom midfielder Jake Livermore was escorted down the tunnel at ​West Ham's London Stadium on Tuesday night after a clash with a fan, ​the Mirror have reported.

The Hammers have launched an investigation into allegations that the fan in question shouted abuse relating to the player's baby son, who died in 2014.

The England international was withdrawn in the second-half of his side's 2-1 defeat, replaced by Hal Robson-Kanu.

Witnesses reportedly saw Livermore involved in a heated confrontation with a home supporter, before he was ushered away.

Stewards surrounded the tunnel after the incident, while ​West Brom coach John Carver remonstrated with officials.

“The only thing I know is that I saw Jake in the crowd which disturbed me a bit," said Baggies boss Alan Pardew after the game - quoted by ​the Birmingham Mail. "He wouldn’t have done that unless he was provoked severely. I’ll talk to him and we’ll go from there.

“Of course [we’ll investigate it]. I haven’t had a chance to speak to Jake, I’ll speak to Jake and we’ll go from there.”

The club have since ​released a statement, which read: "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."

Livermore, who joined West Brom last summer, tested positive for cocaine in April 2015, although it was later revealed that he had taken the substance to help with the grief of the death of his newborn child.

The 28-year-old made his 22nd appearance of the season against West Ham, but was unable to inspire his side to victory while on the pitch.
