Milton, 52, told the TV3 channel that he intended to increase his ownership in AIK Thursday, saying he wanted to gain "influence" in AIK and convince fans involved in hooliganism that "football is not about fighting."
AIK, currently fifth in the Swedish rankings, has experienced an increase in hooliganism, with the team's fans organizing mass fights with fans from rival clubs.
Club spokesman Johan Wiback told the Expressen newspaper that as a publicly traded company, AIK "cannot do anything [about Milton's ownership]. Anyone can buy shares in AIK."
AIK board chairman Per Bystedt told tabloid Aftonbladet that the club did not want to be linked with porn.
"Our values are very different from what I consider the porn industry to have," Bystedt said.
Milton recently made headlines in Sweden after tax authorities won a case in the Supreme Administrative Court that ruled he owed back taxes of 650 million kronor for the time period 1995-99. The National Tax Board has maintained that Milton did not move to Spain in 1989 as he has claimed, citing his ownership of several cars and a mansion southwest of Stockholm.
