The new Twitter app allows users to post live video streams. Clips must be watched live and cannot be replayed.
Those planning to use the app to stream ringside, courtside or stageside in this country may be banned from future events and could face legal action. Filming and streaming live events is banned in the terms and conditions of most ticket sales for prime sporting and entertainment shows.
