Bathers at a nudist beach in northwest Germany say they were insulted and threatened by a group of “Mediterranean-looking men,” one of whom reportedly shouted “Allahu Akhbar” at them.
Staff at the Freibad Xantener Südsee said they were forced to call the police after the men refused to stop abusing naked bathers at the resort, which is near the town of Wesel.
Eyewitnesses told the German newspaper Rheinische Post that the group “looked Mediterranean,” had beards, and wore their hair long.
They are alleged to have shouted “Islamic remarks” including “Allahu Akhbar,” according to another German newspaper, Junge Freiheit.
Germany is on high alert after a spate of lone wolf attacks in the country left 15 people dead and dozens more injured.
At least two of the attackers had links to Islamist terror groups.
It is understood that two of the men swam onto the nudist beach, while the other four arrived on foot.
When staff intervened and told the men to calm down, they left the beach and instead went to the resort’s water ski facility, where they continued to abuse guests.
The incident, which took place on Wednesday, was not reported to German police until the following day.
They are investigating and have interviewed several eyewitnesses.
It comes amid heightened tension between refugees and locals in Germany due to a huge influx of asylum seekers from Syria and Afghanistan.
Last Sunday, a 27-year-old Syrian refugee blew himself up outside a bar in Bavaria in what was described as an attempted Islamist attack which injured twelve people.
On the same day, a pregnant woman was hacked to death by a Syrian man in the German town of Reutlingen. Police described the incident as a “crime of passion.”
And last week, a teenage refugee from Afghanistan attacked passengers on a regional train in Bavaria with an axe, seriously injuring four of them, after pledging allegiance to the Islamic State in a video posted online.
The worst attack was carried out by a German-Iranian teenager who gunned down nine people outside a shopping centre in Munich on 22 July.
Angela Merkel, the German Chancellor, has faced a storm of criticism over her “open door” refugee policy, which brought more than one million asylum seekers to Germany last year.
In Bavaria, where the attacks took place, the region’s leader has demanded tighter security and tighter immigration policies.
“Each attack, each act of terrorism, is one too many. Islamist terrorism has arrived in Germany,Horst Seehofer said on Tuesday.
“We need more security in Germany. People are riled up, full of fear, and that is completely understandable.
They need reliable answers from politicians and not endless debates and justifications.”
