A dangerous sexual predator, who repeatedly abused an under-age girl in Bradford, has been locked up indefinitely.

Juraj Badi, 45, who had served two long sentences for rape in his native Slovakia, subjected his victim to sexual intercourse over a prolonged period when she was aged 14 and 15.

Sentencing him to an indeterminate prison sentence for public protection yesterday, Judge James Spencer QC told Badi: “You used her for yourself and your own sexual gratification.

“I have no doubt whatsoever that you are a dangerous man and you present a significant risk to members of the public of serious harm. You do not see that you have done wrong. You will abuse other children in the future, I have no doubt, if you are able.”

Badi, a Slovakian, of Brandfort Street, Lidget Green, Bradford, pleaded guilty to two charges of sexual activity with a child on the second day of his trial on rape charges, of which he was then cleared. Badi made the girl pregnant.

Leeds Crown Court was told that Badi had been convicted in Slovakia of sexual activity with a child in 1983, rape in 1988, for which he received a seven-year jail sentence, and another rape for which he was imprisoned for eight years in 1994.

His barrister, Andrew Smith, insisted the relationship with the girl in Bradford had been consensual. He said the judge should consider the social and cultural differences between the UK and Slovakia, where consensual relationships between an older man and a 15-year-old girl were found to be acceptable.

But Judge Spencer said that, as an adult, Badi would have known the girl was unable to make such a decision for herself, and “in any event, you were not concerned in the slightest”.

Badi will have to serve a minimum of three years and 51 days – the equivalent of an eight-year sentence – but will not be released until the Parole Board is satisfied he was not a danger.

Investigating officer Detective Constable Kate Hickson, of Operation Topaz, said after the case: “Badi systematically abused his victim over a number of years, controlling her through threats and physical assaults. He is clearly a very dangerous man.

“I would like to commend the victim and her family in this case for the trust she has placed in the police and criminal justice partners, having the strength to come forward and for her continued support over what has been an extremely difficult and emotional time.

“I would ask other victims of sexual crime to come forward in the knowledge that we will take them seriously, investigate professionally and achieve justice.”
