German police are defending a decision to screen hundreds of North African men who had gathered for New Year celebrations in Cologne, saying it prevented a repeat of the sexual assaults in the city of a year ago.
Responding to criticism on social media that they had racially profiled suspects, Cologne's police chief said the men fitted the description of potential criminals.
Police said they had prevented a repeat of the assaults and robberies suffered by hundreds of women in Cologne a year ago by screening 650 mostly North African men on New Year's Eve.
Police detained and screened many of the men at the main railway station as they headed towards the centre of Cologne in western Germany, where the attacks a year earlier fuelled criticism of Chancellor Angela Merkel's open-door migrant policy.
Cologne police chief Juergen Mathies did not say how many of the men were subsequently allowed into the city centre but denied that the checks amounted to racial profiling.
He also said many of those detained had been aggressive.
"This was clearly about preventing similar incidents to last year," he told a news conference.
"A large part of this group that was checked was such that criminal acts were to be expected. That is why we took this clear approach."
Police arrested 92 people - including 16 Germans and 10 Syrians - during Saturday night's celebrations in Cologne.
Police also installed new video surveillance cameras to monitor the station square.
Many of the suspects in the attacks a year ago were of North African and Arab appearance, the police have said.
Those attacks helped fuel the rise of the anti-immigration Alternative for Germany (AfD) party, which hurt Mrs Merkel's conservatives in a series of regional polls last year and threatened to erode her support in this year's national election.
In her New Year's address to the nation, Mrs Merkel said Islamist terrorism was the biggest test facing Germany.
Although the migrant flow into Germany has slowed sharply, Angela Merkel is under pressure from the AfD and her party's conservative Bavarian allies to take tougher action after more than one million asylum seekers arrived in Germany in 2015 and 2016.
