There is no evidence of Mossad involvement. Far from me to defend Israel's spy agency but the article only mentions a possible connection to Azerbaijan.

This one doesn't since it's a US outlet and they don't have free speech in the US, on Israel-related matters. The Irish Times reported the Israel connection though.

"they don't have free speech in the US, on Israel-related matters"

Is the sky in your world green?

The Irish Times reported an Israel connection regarding a separate case involving him, the Block Scandal. As far as I am aware that case did not involve giving out state secrets to other governments. This article mentions Der Spiegel which reported the investigation on the possible Azerbaijan connection.

Azerbaijan doesn't give a rat's *** about German state secrets. :) It's either BS or they served as a proxy.

Azerbaijan is a former soviet republic. So them playing role of a proxy for Russia or stealing secrets to sell to Russians makes sense to me.

The Russians claim otherwise - https://www.rt.com/news/646794-german-spy-chief-arrested/ -... According to them, his private agency also sub-contracted some high-profile kidnapping to Yaakov Perry, the former chief of Israel’s domestic intelligence agency, Shin Bet.
