This happened to my ex flatmate in 2019. He's a Chinese Indian guy from Kolkata (relevant), was working an entry level job at a FAANG company going home after a night shift on his bike.
Drunk local on a bike starts swerving around in front of him, he tries to overtake but is forced to stop because the guy blocked his way and braked hard. This happened near Marathahalli.
Drunk guy comes up to him and starts blabbering dumb shit, accusing him of stealing his phone followed by racist comments. Then proceeds to call the cops from his phone which was actually in his own pocket (make of that what you will).
Cops take them both to the station. Drunk guy cooks up some story in Kannada and leaves. Cops start grilling my flatmate, more racist comments, threaten to go check his room (our flat) and start bullying him. Said he kind of looked like one of the wanted posters they had. He knew basic kannada so he had an idea of what racist stuff the cops were saying about him that they thought he didn't understand.
He was messaging me updates in the brief moments that he had his phone with him, which was confiscated by cops for the most part.
Eventually they let him go because there was literally no crime and no proof.
Tl;dr - He had to spend 6+ hours in the station because of one drunk asshole and racist cops who just liked to give non-locals a hard time for no good reason.
