MANCHESTER, England (AP) — Police in Scotland are investigating “threatening” messages sent to referee Kevin Clancy as another British soccer official is thrust into the headlines for the wrong reasons. Clancy was criticized for his performance in Celtic's 3-2 win against Rangers in the Scottish Premiership on Saturday, leading to a host of abusive messages. The Scottish Football Association said it had “referred a significant volume of threatening and abusive emails to Police Scotland after personal and professional contact details” of the referee were published online.
