GRENOBLE, FRANCE — A 46-year-old French woman and her three young daughters were seriously injured when they were stabbed by their neighbor at an Alpine vacation resort on Tuesday. <br /> <br />Moroccan national Mohamed Boufarkouch, 37, was arrested after he stabbed the girls with a small folding knife outside their vacation chalet in the resort of Garde-Colombe in southern France, the Telegraph reported. <br /> <br />An initial report said Boufarkouch attacked the girls because they were scantily dressed. <br /> <br />French television channel TF1 reported that Boufarkouch was angry the girls were wearing shorts and may have acted out of religious motives, according to the Telegraph. <br /> <br />However, local prosecutor Raphael Balland said the report was false. He also denied the attack was linked to religious fundamentalism. <br /> <br />The youngest girl, aged 8, was airlifted to hospital with a punctured lung. Her sisters, aged 12 and 14, were being treated for serious but non-life threatening injuries. The mother was being treated for an injury to her sternum. <br /> <br />Boufarkouch, who lives in Paris, was at the resort with his pregnant wife and two children. The two families were staying next door to each other. <br /> <br />Reports said the girl’s mother helped Boufarkouch the previous day by bringing him medication when he was sick.
