What happened to Suren Arakelov? I heard that Professor Suren Arakelov got mental disorder and ceased research. However, a brief search on the Russian wikipedia page showed he was placed in a psychiatric hospital because of political dissent. 
Since in Soviet Union days a healthy person can get into psychiatric hospital because of "sluggish schizophrenia", it is unclear to me whether he was really sick. Perhaps he was tortured and that is why he stopped research? Is he still alive? Does he still give lectures in Moscow?
The whole Arakelov theory obviously owe its foundation to Arakelov's ground-breaking work in 1970s. The invention of Faltings height is stemed from Arakelov theory. I am wondering what is the current situation of Prof. Arakelov (no email, no physical address, only some dubious reports on wikipedia). The whole situation sounds like John Nash, except Arakelov have not recovered. 
I ask at here because I honestly do not know who else to ask (I do not know anyone else graduated from Gubkin Russian State University of Oil and Gas in my university). 

Update:
I received an email forwarded from Prof. Beilinson, written by Prof. Bogomolov, which clarified the matter completely. The alleged event did not happen, even though Prof. Arakelov was warned by the government for his actions. Instead Prof. Arakelov was sick due to private personal reasons. As a result I am voting the post to close. 
Thanks for everyone's help in this matter. 
 A: There are memoirs by Mikhail Zelikin in Russian. He knew Arakelov personally and quite explicitly describes what happened to him. 

Через несколько дней произошло следующее. Был арестован Солженицын. Сурен Аракелов, верный ученик и последователь своего великого учителя, решил вступить в борьбу с режимом. Он изготовил два плаката — на грудь и на спину — с надписью: “Свободу Александру Солженицыну” и отправился на Красную площадь. Там его и арестовали и отправили прямехонько в институт Сербского. Выписали его через пару лет. Игорь Ростиславович приехал его навестить и поразился произошедшей перемене. Внутренний огонь его души был наглухо затоптан и погашен. Его не интересовали ни математика, ни политика, ни даже внимание его некогда обожаемого учителя. Через некоторое время он женился, нашел какую-то рутинную работу и превратился в добросовестного обывателя. Специалисты из института Сербского на этот раз блестяще продемонстрировали свою профессиональную состоятельность. Они превратили гениального мальчишку в “нормальную” посредственность.

In English:

A few days later the following happened. Solzhenitsyn was arrested. Suren Arakelov, a loyal disciple and follower of his great teacher [Shafarevich], decided to fight the regime. He made two posters - on his chest and on his back - with the inscription: “Freedom for Alexander Solzhenitsyn” and went to Red Square. There he was arrested and sent straight to the Serbsky Psychiatry Institute. He was discharged a couple of years later. Igor Rostislavovich [Shafarevich] came to visit him and was amazed at the change that had occurred. The inner fire of his soul was trampled and extinguished. He was not interested in mathematics, or politics, or even the attention of his once beloved teacher. After a while he got married, found some routine job and turned into an average man. On this occasion the specialists from the Serbsky Institute have brilliantly demonstrated their professional competence. They turned a genius into a “normal” mediocrity.
