Police waited 13 days to apprehend a man who is accused of the brutal gang-rape of an 18-year-old girl during that time, despite there being a warrant out for his arrest which specifically warned he was dangerous.

The suspect, identified only as 21-year-old Majd H., allegedly orchestrated the rape of a teenage girl by at least 8 men in a wooded area outside a Freiburg nightclub on October 14.

German newspaper BILD reported that an arrest warrant for the suspect, who was known to police and had a prior conviction for assault, had been issued on October 10.

According to BILD, the warrant clearly noted how dangerous Majd H is and categorized him as a multiple offender.

It went on to say that there was a high probability he might commit other significant, similar offenses, including grievous bodily harm, sexual coercion and exhibitionism.

Finally, it issued a stark warning: To prevent worse, arrest him urgently.

The police waited 13 days until October 23 to arrest Majd H. along with other criminals, at first citing investigative tactics as the reason.

Now it is said that they were unsure about the whereabouts of the alleged chief offender.

On the night of October 14, Majd H, who is originally from Syria, allegedly gave the victim drops of a date-rape drug before inviting at least seven friends (though it could be as many as 14) aged 19-30, to take turns to rape her.

The attack, in the shrubbery outside the nightclub, lasted four hours.

After the incident, Freiburg's Police Commissioner Bernhard Rotzinger, 62, Interior Minister Strobl's State Secretary Julian Würtenberger, 61, and Mayor Martin Horn, 33, met for crisis talks in the town hall.

They discussed how to improve the security situation in the southwestern town in the Baden-Württemberg region of Germany.

According to BILD, Majd H. came to Germany in 2014. He is a Syrian Kurd, and his family including parents, brother and uncle also live in Freiburg.

His father told BILD: 'Majd was always aggressive after our escape, had trouble with the police, was even previously sentenced because he had hurt someone.'
