Travis Scott voiced fears over being insanely outnumbered by Miami Beach Police officers leading up to his arrest … new video shows.

In the police body cam footage, obtained by TMZ, Travis is arguing with cops and keeps saying he feels scared by what he thinks is an over-the-top police response.

Travis does NOT go quietly into the night as he’s arguing with cops at 1:15 AM … and there’s an intense build-up before officers throw his hands behind his back and slap on a pair of handcuffs.

Travis was arrested back in June for disorderly intoxication and trespassing … after police said they were called to a marina near Miami Beach where Scott was allegedly arguing with a yacht worker.

In the video, cops escort Travis away from the boat and let him leave … but he comes back to the yacht to grab his belongings, and that’s when cops intercept him, and he gets scared.

TMZ broke the story … prosecutors on Thursday dropped the disorderly intoxication charge against Travis, but the state of Florida is moving forward with a misdemeanor trespassing charge.
