Justin Bieber was kept waiting at an airport in Florida on Sunday (18Aug13) while sniffer dogs checked his team's luggage for drugs. The Baby hitmaker made headlines last month (Jul13) when Canadian border patrol police in Michigan found marijuana and drug paraphernalia on board one of his tour buses. Officials are clearly now on the lookout for the teen superstar as authorities at Florida's Fort Lauderdale International Airport stopped his entourage on Sunday to send in the drug dogs. The crafty canines checked bags in a parking bay as Bieber kept himself busy posing for photographs with fans nearby, according to TMZ.com. Nothing incriminating was found during the search,and Bieber and his crew were allowed to board their flight. The singer had been partying with Jay-Z and Kevin Hart in Miami, Florida over the weekend (17-18Aug).
