Are you deliberately obfuscating things or is it you just can't help yourself?
1. There is no proof or indication that is indeed the case. It is mere speculation on your part.
2. This entirely unclear from Sky's stament. From the statement it seems more likely than not that it was an official OOC testing that rang the alarm bells on Henao at Sky.
It seems Sky with the full cooperation of its' riders and access to these test results (also in the statement).
3. We know who the somebody is. It was Henao's agent who leaked it to Gazetta dello Sport in Italy. UCI and WADA in principle never issue official statements if they have any suspicions or a case pending. After the leak Sky went in full damage control mode. I wonder why?
