Belgian police have blamed banned Lokeren supporters for causing trouble as violence erupted after Hull City's Europa League match.
• UEFA: 'No case' over Lokeren trouble
City fans were pelted with glasses and bottles before they were "bottle-necked" by police when trouble broke out following the Tigers' Europa League defeat on Thursday night.
Supporters, including families with young children, returned to Hull over the weekend, and spoke of their shock at events in Belgium.
After the trouble broke out, three Hull City and two Lokeren fans were arrested for public order offences.
Now, police in Lokeren are looking for banned fans from the Belgian city who they say were heavily involved.
Commissaris Rudi De Clercq said: "There are 61 risk Lokeren supporters who are banned from the football stadium.
"We know that some of them were involved with the problems before and after the match outside the stadium.
"We are now collecting evidence.
"We will use this evidence in our reports, which will be sent to the Belgian Home Office.
"Like always, we make every effort so the persons who were involved will be punished."
Just hours before trouble broke out, City and Lokeren fans had been singing and drinking together.
However, Hull supporters came under fire as they were escorted by police from the stadium past De Mierennest pub – a known haunt of hardcore Lokeren fans – despite previously being told to stay away from there.
Hull City say they have spoken to police to try to establish what happened in Belgium and that their main priority was making sure fans returned home safely.
Meanwhile, one pensioner has told how she was pushed by Belgian police as the fans were escorted away from the ground.
Jean Dennett, 71, of Dunswell, said: "I was trying to get to my brother and sister-in- law when a police officer shoved a shield in my face.
"Luckily, one of the Lokeren supporters spoke to the officers and they let me through.
"It was an awful experience. I was petrified and it was very distressing.
"My father was a groundsman for Hull City and I have supported them for years.
"I've never experienced anything like this and I won't be going to another European away game."
"But I didn't see any Hull City fans cause any trouble."
