Manchester United believe members of The Sun newspaper knew about the attack on the house of Executive Vice-Chairman Ed Woodward in January before it happened.
United also say those behind the story "ED DEVILS Man Utd fans throw flares at Ed Woodward’s house in shocking scenes as anti-board protests continue to escalate" were even present when flares were thrown into Woodward's Cheshire residence.
As a result, the Premier League club lodged a formal complaint to the Independent Press Standards Organisation (IPSO). United announced the complaint on the club's official website on Friday:
"The Club believes that The Sun newspaper had received advance notice of the intended attack, which included criminal damage and intent to intimidate, and that the journalist was present as it happened.
