Birmingham City say the club is "disappointed" with QPR and the Metropolitan Police for statements they gave following crowd disturbances at Saturday's match.
There were a number of incidents inside and outside the ground, during and after the game, and police say three men have been arrested.
One was arrested for a racially aggravated assault on a police officer, one for pitch encroachment and the other for a public order offence. All have been bailed pending further enquiries.
One incident saw two rival fans confront each other on the pitch, and there were also reports of coin throwing.
In a statement Birmingham said: "We note allegations of coin throwing arising from the match at QPR on Saturday and we stress that the club will take the strongest possible action in dealing with any individual found to have indulged in such a deplorable act.
"The club also wishes to express its extreme disappointment that statements were released to the media during and after the match by QPR and Metropolitan Police without consultation with Birmingham City FC or West Midlands Police.
"A number of issues have since been brought to our attention from Saturday's match in regard the stewarding and policing that are of concern to the club and our supporters.
"We read from the Metropolitan Police's statement that three men were arrested, one for pitch encroachment. The QPR supporter who walked round pitchside to confront Birmingham City supporters was, we understand, not arrested.
"We will be making official representation to QPR, Metropolitan Police and West Midlands Police about these issues in order to ascertain the full facts of Saturday's events and gather evidence."
