Russian space official arrested for treason; father died in a fall from a window in 2007
There's all kinds of stuff to unpack here; it's unclear when the alleged work for a NATO country happened. But I find it notable that his father died in one of those "fall from a fifth floor window" incidents while investigating Russian arms sales to Syria and Iran.
Russian space official Safronov arrested for treason
...
Safronov used to be a military reporter at the business dailies Kommersant and Vedomosti.
Roskosmos said in a statement (in Russian) that former journalist Ivan Safronov's arrest was not linked to his current job there.
Russian security service the FSB said he was suspected of espionage for a Nato country, Ria news agency said.
...
However, Kremlin spokesman Dmitry Peskov told the BBC: "As far as we know this is not linked to his prior journalistic activity in any way."

2007:
Safronov, a military affairs writer, fell from a fifth-floor window on Friday at the Moscow apartment block where he lived.
His newspaper said at the time of his death he was investigating reports of alleged Russian plans to sell sophisticated missiles to Iran and fighter jets to Syria, via Belarus.
Prosecutors quoted by Russian media say they are investigating the possibility that he was "driven to suicide".
But friends and relatives of Safronov told Kommersant that they knew of no reason why he would commit suicide.
