London, Nov 30 : Officials have launched an investigation against "British Fritzl" for his involvement in other unsolved sex attacks around his hometown.
The 56-year-old businessman was last week given 25 years of life terms for abusing his daughters over a period of at least 25 years and fathering nine children with them.
However, now it is feared that he may have committed other crimes as well and thus officers are trawling through unsolved sex attacks in areas where he used to live.
"Here we have a man who showed a blatant dis-regard for what is right and wrong," The Daily Star quoted a police source as saying.
The source added: "The type of abuse he inflicted on his daughters has rarely been seen before, so it is only right we examine the possibility he may have committed other crimes. We know he used to attack his daughters every day but then it suddenly became two or three times a week. Why was this? Was he pursuing his urges elsewhere?"
The case bears stark similarities with that of Austrian sex beast Josef Fritzl, who locked his daughter Elisabeth in a dungeon and fathered seven children by her.
And the "British Fritzl" moved his girls around remote areas in South Yorkshire and Lincolnshire to avoid detection.
The abuse started when they were both under ten years old.
According to sources, police in both counties have dedicated "cold case review teams" which are believed to be probing unsolved sex attacks.
