Police are appealing for calm tonight after threats were posted online against Browns Bar in Coventry which refused to serve two soliders in uniform.
They were pall bearers at the funeral of their comrade, Corporal Michael Thacker, who was killed in Afghanistan and had gone to the bar to buy hot drinks before the ceremony.
The story has triggered a furious response on Facebook with more than sixty thousand people signing a campaign attacking the bar's owner.
And there have been more sinister threats warning of attacks against the bar.
Today the owner, Ken Brown, spoke to Central Tonight and apologised for what happened on Monday.
Corporal Thacker's widow has accepted the apology but police are now concerned about the anger online.
