Looks like they're receiving a few home truths by somebody from Avon and Somerset Constabulary who posts on their site:

1 hour ago, Can't stand me now said:
Julie can you tell us if any Cardiff fans have been arrested I.e the one who threw the flare / banger into the city end?

Sounds like a big stitch up just like a few years ago. Look forward to seeing the cctv footage of this, like mentioned previously I'm sure it will be edited to suit.

There were no Cardiff fans arrested from the incident as it happened in Bristol city area.

the fire cracker was thrown by a Bristol city fan who attempted to throw it over the segregation fencing however it did not go high enough and bounced back into the crowd. Many witnesses saw this happen including me.
