“We welcome the Scottish FA and Police Scotland investigations, the findings of which must be made public,” the former Rangers full-back said in a statement.
“There must be stronger protections and accountability, with increased sanctions for individuals and clubs where player safety is compromised.
“In addition, wider and more consistent use of Football Banning Orders for those who engage in violent, abusive or dangerous behaviour is required.”
Wishart stressed that “player safety is not optional” or “negotiable” in what is “a footballer’s workplace”.
“What unfolded is yet another stark reminder of the escalating risks faced by professional footballers in Scotland simply for doing their jobs,” he said.
“No employee in any other sector should be expected to tolerate threats, intimidation, or physical danger while carrying out their duties and footballers cannot be treated differently.”
Two youths have also been charged after a brick was thrown at a supporters’ bus in Dumfries after Saturday’s Scottish League 1 match between Queen of the South and Stenhousemuir.
“This is not a phenomenon solely for the Old Firm,” Wishart pointed out. “Sadly, there have been incidents across the country, many of which have led to clubs making strong condemnatory statements.
“When players are placed at risk, the consequences extend beyond football.
“There are serious questions raised about workplace safety standards and potential legal ramifications for clubs, governing bodies and individuals who fail to uphold their duty of care.”
Meanwhile, the Football Safety Officers Scotland issued a statement in which it “unequivocally” condemns the “unacceptable conduct” of “a minority of supporters” and backs the response of its members on duty on the day at Ibrox.
“Such behaviour brought shame upon both clubs and created risks to the safety and security of police officers, stewards, players, staff and fellow supporters,” it said.
“This behaviour does not reflect the values of either club, or the wider football community.”
