Halsey the subject of Twitter abuse

Referee Mark Halsey was the victim of Twitter abuse following the Barclays Premier League fixture between Liverpool and Manchester United yesterday.

Halsey, who was diagnosed with throat cancer in 2009 but returned to refereeing in March 2010, sent off Liverpool midfielder Jonjo Shelvey for a challenge on United defender Jonny Evans and awarded a late penalty to United which Robin van Persie converted to seal a 2-1 win.
