Daniel Rabinowitz has vowed to punish the perpetrator after the on-going feud escalated between Oakhill and Maccabi Manchester Yellow.
It is believed a derogatory email was sent to Yellows boss Anton Radiven in the wake of a fresh row between the two warring MJSL teams.
Just a week after the JC Sport revealed how Radiven had ordered his players off the pitch in protest over the pitch conditions, the bad blood continued when they met again on Sunday.
Radiven has issued a complaint over the conduct of Oakhill in the wake of the students’ 7-2 win.
But an email to Radiven, via a fake account, branded his actions damaging to the league and urged him to resign from his post.
Oakhill player manager Rabinowitz said: “That has no place in this in football or society. I can assure you there will be punishments if the guilty party is found. It was a stupid, idiotic and childish act.
"Nobody has stepped forward as of yet, but we are looking into the incident. We are taking it seriously. As a club we can only apologise to Anton."
Anton Radiven responded: ""We can confirm that an email was received which the contents of which disappointed us greatly.
"It's disappointing to not that anyone connected with the MJSL would act in such a way and we have placed the matter in the hands of the league executives."
