DNA can't split twins Mohammed and Aftab Asghar in rape case in Reading DNA testing in a UK rape case has been unable to tell apart a set of twins Source: Supplied A PAIR of identical twins in the UK who can not be told apart by their DNA have both been arrested over the rape of a woman. The Telegraph reports that DNA belonging to either Mohammed or Aftab Asghar or both of them was found at the crime scene of a rape that occurred in November 2011. Details of the incident have been withheld but the prosecutor has asked for more time to work out whether both should be tried for the crime. The twins, from Reading in Berks, have meanwhile been granted conditional bail. Identical twins share matching DNA but have different fingerprints. In February, two identical 24-year-old twin brothers were held in Marseille, France, by police hunting a rapist as their genetic codes were so similar that normal DNA tests could not tell them apart.
