An 83-year-old man who sexually abused and raped four girls over the course of more than two decades has been jailed. Sazzad Miah, 83, of Jermyn Close, Cambridge, was convicted of 18 separate counts - six of them rape - after a trial at Cambridge Crown Court. Two of his victims were as young as four, another was aged five - and a fourth was aged 10, the court heard. Miah was arrested last October after police were tipped off about the abuse, which dated back 23 years. The defendant, who had denied all the charges, was jailed for a total of 19 years and placed on the sex offenders register for life.
