>> Investigations into his behaviour started after emails were found in which he agreed to hand over inside information in return for payment.

I'd be curious to see how exactly this occurred. The above blurb is the only mention of it in the entire (super short) article.

I'm curious for two reasons:

1) I work for a big tech company and have a technology consulting services company on the side. I'm curious to see how my outside emails may be eavesdropped upon.

2) Were those emails obtained legally? I can't imagine he was using his apple email to send the emails, does this mean they went through his personal email? If so, was this done legally?
