Weekend #1 numbers were slightly under-reported, we reported that 58 people were arrested during the first weekend, but it was raised to 81.
Now for Weekend #2, the total was 86 arrests, mostly for minor drug offenses and the ever-present problem of gatecrashing (which is such a bad idea people).
The grand total therefore is 167 arrests at Ultra. Plus a HEFTY sticker problem.
