I was reading a story and read following lines:
Few robbers tried to threat a restaurateur so that he should return money to their boss. Restaurateur defied their warning and ran away from there. While running, he and his assailants reached the roof of an old building.
I think "his" shouldn't be used along with "assailants" here, as its meaning appears to me that "assailants" were working for the restaurateur. However, the writer meant that the "assailants" were chasing the restaurateur in order to frighten him. So, I think that "his" should be replaced by "the" here.
