A German politician is facing a police investigation over inflammatory comments made on New Year's Eve.
Beatrix von Storch, deputy leader of Germany's far-right AfD party, had her Twitter account suspended on Monday following anti-Muslim remarks.
She accused Cologne police of appeasing "barbaric, gang-raping Muslim hordes of men" after they tweeted a new year message in Arabic.
Police are deciding whether she should be charged with incitement to hatred.
The police force tweeted its message in a number of languages, including English and French as well as Arabic and German.
Twitter suspended Ms Storch's account for 12 hours in response to her post, saying it breached the site's rules.
She then re-posted the same message on Facebook, where it was also blocked for reasons of incitement.
Police in Cologne told German news magazine Der Spiegel that it was investigating if the member of parliament had committed a criminal offence, but stressed that doing so was normal procedure.
The controversy comes only months after Germany enacted new hate speech laws.
Ms Storch's party defended her comments, claiming that the removal of her remarks was a form of censorship, reports BBC.
Writing on Facebook, AfD leader Alice Weidel wrote that authorities were submitting to "imported, marauding, groping, abusive, knife-stabbing migrant mobs"..
