Following in a similar fashion to the first night of Nocturnal Wonderland which saw 111 people arrested for various offences, most of which are presumably drug-related, the second night saw even more people arrested – 141 to be exact – bringing the weekend total to 252.
Again, the arrests happened for a myriad of reasons, most of which were drug related such as possession, drug sales, being under the influence, and more. One festivalgoer was also hospitalized for injuries suffered from assault, but unlike the first night, no hospital attendees were admitted for drug-related reasons.
The festival is set to continue today which would probably bring the total amount of arrests made over the festival weekend to close to 400. 
Saturday’s attendees totalled 25,762 making the arrested percentage of the entire festival a respectable 0.55%.
