Additional security on duty at Ascot after 'beer throwing' incident

Additional security has been put in place at Ascot following Friday's incident which saw a pint of beer narrowly miss Andrea Atzeni.
Atzeni was going down to the start for the last race when a member of the public threw his drink, which only just missed Atzeni and his mount Appeared, who went on to be second in the Duke of Edinburgh Stakes.
