A Syrian migrant has been arrested for allegedly raping a 25-year-old woman in the same German city where an Afghan man raped and murdered the teenage daughter of an EU official.

The victim told police at around 6.30am on Saturday morning that she had been attacked in Colombi Park in Freiburg, in the south-western state of Baden-Wuerttemberg.

Police and forensic experts searching the area where the assault took place found the suspect's backpack - complete with owner's personal details and identifying documents.

Officers arrested the 23-year-old Syrian at a refugee shelter in the district of Breisgau-Hochschwarzwald at around 2pm.

It comes after one of Freiburg's most shocking murder cases came to an end in March when asylum seeker Hussein Khavari was handed a life sentence for the rape and murder of Maria Ladenburger.

The Afghan national, who age and origin is uncertain, raped and murdered the 19-year-old medical student in the university town in October 2016.

In Saturday's alleged rape, the woman said she had earlier been approached by two unknown men on the railway road.

One of them then follow her into the park where he allegedly raped her.

She fought back and finally managed to call the police and the perpetrator fled the scene.

The 23-year-old, who has not been identified, has been presented to a magistrate and is currently in detention. He denies the allegations.

It comes after three attempted in Freiburg over the past weeks, but in those cases, the victims managed to fight off their attackers.

The police have accused the government of not focusing enough on victim protection.

State chairman of the Baden-Wuerttemberg police union Ralf Kusterer said: 'We have to move away from perpetrator protection to victim protection.'

Khavani's case stoked a fierce public backlash against the mass influx of migrants in Germany especially when it emerged that he served time in jail for attempted murder in Greece before his arrival in the country.

He pushed Ladenburger, whose father is a senior legal adviser to the European Commission in Brussels, off her bicycle as she was riding home alone from a party, then bit, choked and repeatedly raped her and left her on the bank of a river where she drowned.

In March, he was handed the maximum sentence of life in prison, which under German law means 15 years behind bars, with no chance of parole and the possibility of 'security detention' afterwards if the convict is still deemed to pose a threat to society.

Khavari had been arrested seven weeks after the murder, following a huge manhunt in the town near the French border.

Police had found a black hair partially dyed blond at the scene, then spotted Khavari by his hairstyle on security camera footage and linked him to the crime using his DNA.

As the crime sparked public anger and revulsion, social media users posted sarcastic 'thank you' messages to Chancellor Angela Merkel over her liberal policy that brought more than a million refugees and migrants to the country.

During the trial, prosecutor Eckart Berger reminded the two jurors sitting alongside three judges that 'on trial is a criminal offender and not Germany's refugee policy'.

Khavari arrived in Germany, without identity papers, in November 2015, near the peak of the refugee influx, as an unaccompanied minor claiming to be 16 or 17 and hailing from Afghanistan.

A police officer told the court that Khavari's cellphone and social media accounts suggested he had lived in Iran.

Khavari was initially tried as a juvenile offender, but the court accepted expert opinions, based on X-rays and dental analysis, that he is now aged between 22 and 29

Khavari was sent to live with a German host family in the picturesque town of Freiburg on the edge of the Black Forest, went to a local school, learnt German and received state benefits.

It emerged only after his arrest that he had already committed a violent crime in May 2013 in Greece, where he pushed a woman off a cliff on the island of Corfu, leaving her badly injured.

He was sentenced there in February 2014 to 10 years jail for attempted murder but was granted a conditional release from Greece's overcrowded jails in October 2015.

He fled to Germany, where authorities knew nothing of his criminal past because Greece had only issued a nationwide warrant, and because no match was detected in an EU-wide fingerprint data base for asylum seekers.

Khavari was initially tried as a juvenile offender, but the court accepted expert opinions, based on X-rays and dental analysis, that he is now aged between 22 and 29.

The defendant had admitted to the crime, but claimed diminished culpability because he was under the influence of alcohol and drugs -- a position which his defence said it would argue again in an appeal.

Khavari had also claimed that his father died long ago in a battle against Afghanistan's Taliban.

But Judge Kathrin Schenk dialled a number on Khavari's cellphone and reached his father, who told her through an interpreter that he was living in Iran.
