"I have authorised the Metropolitan Police Service to charge seven men with a range of offences under the Sexual Offences Act 2003 which occurred between May and November 2012.
"All seven are charged with conspiracy to engage in sexual activity with a child.
- Desmond Agyei is also charged with four counts of rape, one count of attempted rape and trafficking a person within the UK for sexual exploitation.
- Edward Kofi Edunya and Perry Murray have also been charged with one count each of rape.
- David Sarpong has also been charged with two counts of rape and one court of attempted rape.
- Ade Atitebi has also been charged with trafficking a person within the UK for sexual exploitation and one count of voyeurism.
- Austin Odisi has also been charged with eight counts of rape and Justin Maynard has also been charged with five counts of rape.
"This decision to prosecute was taken in accordance with the Code for Crown Prosecutors.
"The seven defendants will appear before Thames Magistrates' Court this morning (8/3/13).
"They now stand charged with criminal offences and have the right to a fair trial. It is extremely important that nothing should be reported which could prejudice this trial."
No further action has been taken against an eighth man arrested.
