Simple Caution Affray correct?

[bobsp]

I got a taxi home (7 seater) with my wofe and 3 kids after a friends party, the journey is 2.1 miles, we have walked it before. The driver told me it was �16, which is more than double the normal fare. I was pi$$ed off at that and gave him �10 and got kids and wife out. He came banging in my door and wouldn't go away. The wife gave me another �10, which I gave to him. He then stood on the doorstep aggravating me (why he didn't go and get the change I still dont know) I was mad by then, went out, and started hitting his drivers window. He turned round, and divve towards me at such speed I would have got knocked over, but jumped out of the way.

1 hr later while in bed, bang bang on the door, we will have to force entry. Police (wife had to let them in, they were that loud) got me out of bed, cuffed me, locked me up for the night, took statement in morning, I admitted what I had done, but the driver had added loads of things that had not happened, I paid nothing was one, I threatened with a knife, nothing of the sort happened.

I got a simple caution for affray, and sent home.....

Only now anm I realising what this actually means. He has told the police a load of crap here and I have a caution. What can I do now (this was Sunday am)

I am pretty worried as I need a clean police record for my job...........
