Tekashi69 could potentially spend at least the next week locked up in NYC before he's shipped off to face a judge in Houston.
A rep for the Manhattan District Attorney's Office tells us Tekashi was just arraigned and is now in custody until a tentative date of July 20. We're told authorities from Houston are then expected to pick him up on an arrest warrant issued by a judge back in May.
TMZ broke the story ... 69 was arrested at JFK Airport Wednesday when he landed after his European tour. Cops picked him up on the Houston warrant for allegedly choking a 16-year-old.
Tekashi had a show scheduled Friday in New Jersey, but we're told it was postponed prior to his arrest, and all ticket holders have already been refunded.
