The man suing Odell Beckham for an alleged brutal beatdown at the NFL star's home is escalating the war -- now claiming he has proof Odell tried to illegally pay a woman for sex.
But Odell's team claims it's all BS.
It's all in new court docs filed in California ... in which Ishmael Temple claims he was at Beckham's Beverly Hills home back in January, when the NFL star turned on him and allegedly ordered his employees to beat him up.
Temple claims he suffered major injuries, including broken teeth.
