Police monitor home of Chelsea-Barca ref

OSLO: Police are monitoring the home of Norwegian referee Tom Henning Ovrebo after his decisions in Wednesday's Champions League semifinal clash between Chelsea and Barcelona triggered an outpouring of anger on the internet.

Chelsea issued a statement on Thursday condemning reported threats made against Ovrebo, who British media said had to be "smuggled out" of the country under police escort and advised to change hotels following last night's events.

Chelsea fans were furious Ovrebo did not award them a penalty despite several strong appeals during the 1-1 draw in London which sent Barcelona into the final on away goals.
