Regport Cybercrime in the UK - where?

[Poohnix]

Hi all.

Any UK members who can help pointing me in the right direction to report cybercrime in the UK? I'm not in the UK myself, but represent a UK company whose web site got hacked last night, and the hacker managed to get into our payment API - (my own damn fault - I forgot to delete a test environment when the site went live) - and managed to transfer a decent sum of money to himself... (I'm not going into what/how/etc... for obvious reasons.) We're almost sure to recover the money, fortunately I was online and saw it literally happen in real time and managed to find what happened and stop it, plug the security hole, before it got too far, and freeze the transactions, but I still need to report the crime, and need to know where to turn... since it's a UK company (London), I should do it in the UK.

Thanks in advance for any pointers.
