UPDATE 1-Soccer-Late penalty hands PSG League Cup triumph

(Adds detail, quotes, byline)

PARIS, March 29 (Reuters) - A controversial penalty three minutes into added time gave Paris St Germain a 2-1 win over fellow Ligue 1 strugglers Racing Lens in the French League Cup final at the Stade de France on Saturday.

Substitute midfielder Bernard Mendy scored the winner from the spot after referee Laurent Duhamel ruled that Lens defender Hilton had fouled forward Peguy Luyindula.

The offence looked far from obvious and the penalty decision was met by deafening boos from the Lens fans, whose team had fought back from a goal down and were hoping for extra time.

"I feel we've been robbed and Mr Duhamel robbed us," Lens coach Jean-Pierre Papin told French television channel France 3.

"To lose a final that way is a scandal," the former France striker added.

PSG, who dominated the first half of a lively game but struggled in the second, were not complaining after lifting the trophy for the third time following their success in 1995 and 1998 and winning a ticket to next season's UEFA Cup.

"It was a great final with a (good) half from each side and little bit of luck from us at the end," PSG defender Sylvain Armand told France 3.
