Beginning of the day: South Yorkshire Police asked both clubs to ensure their fans arrived between 10.30am and 2pm for the game.
2pm: The Leppings Lane turnstiles began operating smoothly, but after 2.15pm the volume of fans increased.
2.30pm: The road was closed. Fans were asked over the PA system to move forward and spread out in the space. Officers considered delayed the kick-off but did not.
2.40pm: Large crowds had built up outside the turnstiles.
2.44pm: Fans were asked to stop pushing, though crowding was already bad and the turnstiles were struggling to cope.
2.47pm to 2.57pm: Some external gates were opened to relived pressure on the turnstiles – which caused fans to rush forward and crowd the pens even more. Pressure built up, and narrow gates in two of the pens were opened. Officers though fans were deliberately invading the pitch.

3pm: Kick-off. By this time the crush at the front of the pens was intolerable.
3.04pm: Liverpool player Peter Beardsley struck the crossbar of the Nottingham goal, causing fans to rush forward again. The huge pressure caused one of the crush barriers to break, making the situation even more dire for those pressed against it.
