Milton had been the largest shareholder in the club after assuming an 8.4 percent ownership stake last fall. He reportedly sold his stock to an unknown buyer on Monday for $1.70 per share, the same price he had paid for the AIK shares in November.
When Milton bought the shares, he had said he was interested in helping stop an increase in violence by club fans, and also expressed an interest in owning the whole club.
“I’m going to buy as many shares as possible,” he said at the time.
