POLICE in Germany are hunting a band of immigrant men who lured a 'good samaritan' nurse into a children's' park, beat her unconscious and sexually assaulted her.

Detectives said the attackers pounced on the 28-year-old nursing sister who had just left her shift at the Asklepios Klinik St. Georg in Hamburg on Sunday night.

According to police, the men were crying for help from the adjacent Lohmühle Park and she went to give assistance.

But the cries were bogus, intended to draw her there where the men beat and attacked her.

Later she told police there were five attackers, all of them of African appearance.

Detectives say the men they are hunting are all aged between 20 and 30.

Apparently she described one man as a "giant" who wore a green robe or shirt with "glittery seams" upon it.

He also had red dots painted on both his cheeks.

When she came too she found that her clothes had been ripped off and her money was taken.

But she still had her mobile phone and managed to call emergency services.

The victim told Police that the men did not speak German.

The attack comes as Germany remains jittery about sex attacks by migrants.

Following the mass sex assaults on hundreds of women on New Year's Eve in Cologne in 2015 there have been many sexual assaults carried out by asylum seekers.

The most serious was the rape-murder of a beautiful 19-year-old medical student in the city of Freiburg in October.
