Two-time Formula One champion Sebastian Vettel returned to the top of the standings on Sunday with Red Bulls first victory of the season in a lively Bahrain Grand Prix that went ahead without incident despite protests against it. The 24-year-old Germans 22nd career triumph,and first in the troubled Gulf kingdom,made him the fourth different winner in four races. He was pushed hard in the closing laps by Finlands 2007 world champion Kimi Raikkonen,who finished second ahead of Lotus team mate Romain Grosjean in the Frenchmans first appearance on the podium. Australian Mark Webber was fourth in the other Red Bull for the fourth successive race. It was a difficult race,extremely tough, said Vettel,who closed his eyes and took a deep breath as he stood on the podium. With the main grandstand half empty,and few spectators to be seen elsewhere at a circuit with a maximum capacity of 45,000,the race was a far from normal affair after days dominated by talk of petrol bombs and teargas. There have been almost nightly clashes elsewhere on the island between anti-government protesters and riot police,and teams and organisers could breathe a sigh of relief that the race went off without trouble on the track. Vettel,who had started from pole for the first time this season,made his trademark single-finger salute for the first time since last year after taking the chequered flag. With fuel running low,he was told to pull over and stop immediately at the pit exit which meant he had to run down the pit lane to embrace his mechanics. Vettel now has 53 points,ousting McLarens Lewis Hamilton from the top. The Briton,who finished eighth after two nightmare pitstops,has 49. Red Bull also overtook McLaren in the constructors championship. Di Resta finishes sixth Germanys Nico Rosberg,winner of the previous race in China,finished fifth with a stewards enquiry hanging over him for moves on Hamilton and Ferraris Fernando Alonso. Britains Paul Di Resta was sixth for Force India with Alonso seventh and Brazilian team mate Felipe Massa finally in the points in ninth ahead of Germanys seven-times champion Michael Schumacher in a Mercedes. McLarens Jenson Button retired on the penultimate lap.
