Antoni Imiela denies nine counts of rape against women and girls

An expert said the chance of the DNA matching anyone other than Antoni Imiela was about three million to one.

Mr Imiela, 49, of Appledore, denies nine counts of rape on five women and three girls and kidnap, attempted rape and indecent assault of a 10-year-old.

The court heard the DNA was found on the top and a bra.

The 26-year-old woman was attacked and raped as she walked near Epsom Common in Surrey on August 7, 2002, the jury was told.

Scientist Valerie Tomlinson said she had overseen DNA tests carried out on the blue top, on other fabric from the woman's clothing and on swabs taken from her bra.

She said the mixed DNA profiles were found on each, mainly made up of genetic material from the victim.

Different conclusion

But she added that additional "bands" of DNA were found on the three materials tested - components which she said were represented in the genetic profile of Imiela.

She said: "In this case, if the DNA had originated from a known person unrelated to Mr Imiela, I estimated the chances of obtaining a matching profile to be one in three million."

Defending, Rebecca Poulet QC said that a defence scientist had come to a different conclusion on DNA found on the blue top.

She asked Ms Tomlinson if she had made her findings before or after she had received a "reference sample" containing the DNA profile of Imiela and said: "Are you being as fair as possible to the defendant in that conclusion?"

The series of attacks are alleged to have happened in 2001 and 2002 in London, Kent, Surrey, Berkshire, Hertfordshire and Birmingham

The case continues.
