The occupants of the British Airways first class lounge at Heathrow were probably rather relieved last night that the 30-strong entourage of the US rapper Snoop Dogg were turned away. But Snoop and his minders were not happy and what has been described as a "mini-riot" broke out at terminal one that left the rapper and five of his associates under arrest. Seven police officers were injured. One suffered a fractured hand, the others' injuries were more minor, mostly cuts and bruises.
