Delonte West repeatedly hurled homophobic slurs and said he was a better basketball player than LeBron James during his arrest last week ... and the disturbing scene was all captured on police video obtained by TMZ Sports.
West was stopped by cops in Boynton Beach, FL, on Oct. 19 ... after officers say he was yelling and banging on a local police station's doors.
Cops say he was holding two open containers of alcohol -- one beer, one vodka -- during the episode ... so they ordered him to the ground.
