John Worboys: Met Police reveals it dropped 19 women's allegations against serial rapist

One complaint in particular did 'not pass the evidential test'

John Worboys was found guilty in 2009 of raping 12 women – but police say he could have attacked at least 100 (PA)

A total of 19 further allegations against John Worboys were dropped and not investigated further, the Metropolitan police has announced.

One complaint in particular was deemed to "not pass the evidential test" and was therefore not looked into in more detail.

The Metropolitan Police confirmed there is currently no live investigation into Worboys, who has been dubbed as the "black cab rapist".

In a statement, The Metropolitan Police said: "The Metropolitan Police Service worked closely with the Crown Prosecution Service (CPS) throughout the case of John Worboys.

"Liaison with the CPS continued post-trial, when the Met received allegations from a further 19 women. Each individual allegation was recorded and investigated.

"In June 2009 the CPS were notified of the additional complaints and they provided written advice in response. Each allegation was assessed by police against this advice and a decision was taken by police not to proceed.

"All 19 complainants were notified."

Worboys was found guilty of 19 charges of drugging and sexually assaulting 12 women passengers, in one case raping a woman, in 2009.

He is now set to be released prompting outrage from campaign groups who have described his sentence as "woefully short".

The Metropolitan Police said in 2010 that his alleged victims numbered 102 after more people had come forward following his trial and conviction.

The CPS said: "It would be unlikely that it would be in the public interest to prosecute Worboys in relation to allegations of sexual assault or administering a substance with intent, because of the maximum sentence available to the court."
