PARIS, Dec 15 (Reuters) - Struggling Paris St Germain suffered a 2-1 home Ligue 1 defeat by Toulouse featuring two goals from Sweden forward Johan Elmander on Saturday. The troubled Paris club stay fourth from bottom but could return to the relegation zone after later action and are still without a home win this season. Elmander exploited a defensive blunder to put the visitors in front on 42 minutes before beating an offside trap to double the advantage four minutes into the second half. Former Portugal striker Pauleta reduced the arrears from a penalty in added time after Colombian defender Mario Yepes was fouled in the box. Police authorities had brought the kickoff time forward and implemented reinforced security measures for the game amid fears of crowd trouble. The PSG players left the pitch to the sound of jeers from their fans but no serious incidents were immediately reported. Toulouse climb five spots up to ninth in the 20-strong table.
