The men were taken into custody inside the stadium on Tuesday night by police hoping to have aprehended the men responsible for Michael's death.
After 25 hours the six men were bailed and today they have been released from that bail and are no longer suspects.
Michael's attacker still roams free as the police renew their enquiries.
One of the six Welsh fans arrested, while staying anonymous, has told his story to the Football Supporters Federation.
He writes:
First and foremost may I give my condolences to the family and friends of Mikey Dye. What is most important is how they feel.
I have shared my dreadful experience with the FSF and am posting this message as I feel that having it posted on both message boards will allow me to overcome the nightmare I have endured this week.
For obvious reasons I wish to remain anonymous. I trust the FSF and am thankful for their support. I am a Cardiff City season ticket holder and football is a big part of my life. I often read both message boards but never post.
I was one of the six people arrested over the tragic incident at Wembley on Tuesday night. I have been cleared, and the police will not be taking the incident any further.
Before the game I met two of my friends (who were going to be seated in the England section) but we became separated at a very busy London station. As a result of this separation I had to make my way to the match on my own. I arrived late (just missing kick off) and had no knowledge of the incident. I kept myself to myself during the match.
Towards the end of the game a group of five men (none of which I knew or had any association with) were taken from the stand by the police. They then proceeded to select me from the crowd and I was escorted from the stand.
What happened next will remain with me. It was an extremely worrying time for myself, my family and my friends. I have spoken in detail with the FSF about my experience and they also found it distressing to listen to what I had been through.
Cardiff City FC will pay tribute to Mr Dye at tomorrow's game against Doncaster Rovers.
