The arrest warrants show that the men are 18, 20 and 29 years old. Two are citizens of Somalia and the third in Eritrea. One of them needs interpreting in Somali and another in Arabic. Which means that they most likely are newly arrived migrants.
If the robbery was voluntary or not the story does not reveal.
Two of them are previously convicted. The 18-year-old has committed assaults and drug offences. The 20-year-old is convicted of several cases of theft and drug offences.
One of them is also suspected of a rape that took place in February. After the gang rape, they robbed the woman of her belongings, for which they were also arrested.
They have admitted that all three had sex with the woman but argue that this was done voluntarily. Therefore denying the crimes.
