Concise News reports that the prosecutor said that the boy was apprehended on Monday, due to concerns he could become a repeat offender, adding that the boy was known to police for sexual harassment on two other occasions but under German law, he was not old enough to be prosecuted on those occasions.
The age of criminal responsibility in Germany is 14, he added.
However, the arrested teenager is one of five suspects of the rape case; three 14-year-olds and two 12-year-olds who are all of Bulgarian nationality.
The teenagers are suspected of raping an 18-year-old woman in a wooded area near a playground in the north-western town of Muelheim in North-Rhine Westphalia on Friday evening.
The Local government in Dusseldorf confirmed that the suspects had previously been questioned by police and then returned to their parents after which they were suspended from school.
Two of the five suspects had been known to the Youth Welfare Office (Jugendamt), which had been active in their families.
The Youth Welfare Office was asked to contact the families along with local social services in order to offer help and support, a local spokeswoman said on Monday.
“It is possible that the children will be taken into care,’’ she says.
Police confirmed that the victim left the hospital on Saturday, after being treated.
Investigators declined to give out information about the young woman, citing victim protection concerns.
Sexual assault occurs commonly worldwide and is particularly pervasive in the developing world.
Data available suggests that in some countries, one in five women report sexual violence by an intimate partner and up to a third of girls report forced sexual initiation.
Sexual assault encompasses a range of acts, including coerced sex in marriage, rape by strangers, organized rape in war, sexual harassment (including demands of sex for jobs or school grades), rape of children, trafficking of women and girls, female genital mutilation, and forced exposure to pornography.
Africa is said to have the highest prevalence rate of child sexual abuse at around 34.4 per cent.
Findings from a National Survey carried out in 2014 on Violence Against Children in Nigeria confirmed one in four females reported experiencing sexual violence in childhood with approximately 70% reporting more than one incident of sexual violence.
In the same study, it was found that 24.8% of females’ ages 18 to 24 years experienced sexual abuse prior to age 18 of which 5.0% sought help, with only 3.5% receiving any services.
