People fled the Bellagio casino in Las Vegas as a suspected robber wearing a pig mask sparked fears of a shooting.

The casino and hotel was put on lockdown as reports of an "active shooter" circulated.

Police later called those reports "false", but acknowledged at least one of three suspected thieves had fired shots.
