Håkan Mild has been questioned by supporters before. Several protest actions have been carried out against him and in June a man was sentenced to a fine for having threatened Mild.
After Sunday's Allsvenskan match against Brommapojkarna, the situation is said to have escalated. Home supporters were stopped from bringing in a so-called overhead flag and then chose to boycott the match in protest against the decision.
The threat against Mild is now said to be so serious and high that he needs police protection, reports TV4 News and refers to sources.
"IFK Göteborg has not made a police report. We will not comment on this further and have to refer to the police", says security manager Jonas Arlmark in a statement to TT and other media.
The Göteborg police do not want to comment on the information, according to TV4.
