Is Berbatov's dad a rapist?

There was an exclusive released by The Sun today stating that Dimitar Berbatov has a dark secret and they have said what the dark secret is.

The Sun have said that Dimitar Berbatov's father- Ivan Berbatov - spent two years in jail for his part in a football team “roasting” of a Norwegian girl.
The Sun better hope that they have got this right because it could stir up a load of heartache for the girl in question.

Here is the story, how I understand it:

Ivan was one of six footballers who was jailed for rape of a woman who is only known as Rose.
Summer of 1983 and the Bulgarian team Pirin Blagoevgrad were staying in a hotel in Varna and players 'befriended' a woman in the bar.
Later on the woman told police that they raped her, she picked out seven players in an identity parade, one was Ivan Berbatov.
Six were jailed but they all claimed that they paid her £160 for sex.

This is a very sensitive issue for me due to certain reasons but to bring this out now I think is disgusting.
The press never got hold of this story whilst Berbatov was at Tottenham (as far as I no) and it is just going to stir things up for him and the girl Rose.

In my opinion some things should just be left alone.
