A group of fans have attacked the Cheshire home of Manchester United executive vice-chairman Ed Woodward chanting that he was “going to die”.
A video posted on social media showed a red flare being thrown over a large gate and later spray painted the gates
It is understood that the 48 year old was not present at the time.
A spokesman said: “Manchester United Football Club have tonight been made aware of the incident outside the home of one of our employees.
“We know that the football world will unite behind us as we work with Greater Manchester Police to identify the perpetrators of this unwarranted attack.
“Anybody found guilty of a criminal offence, or found to be trespassing on this property, will be banned for life by the club and may face prosecution.
“Fans expressing opinion is one thing, criminal damage and intent to endanger life is another. There is simply no excuse for this.”
