German police officers will flood the streets of Cologne tonight after 600 women celebrating New Year's Eve were sexually assaulted 12 months ago.
Around 1,800 officers will be deployed this evening - compared to just 140 in 2015 - following the wave of attacks in 2015.
Terror threats around the world also mean there will be a heightened security presence in a bid to prevent a similar incident to the Berlin Christmas market attack earlier in December.
And this time last year, 1,200 women were sexually assaulted by 2,000 men in German cities on New Year's Eve.

In Cologne, police have installed new video surveillance cameras to monitor the station square after women were attacked outside the central train station.
The attacks in Cologne, where police said the suspects were mainly of North African and Arab appearance, fuelled criticism of Chancellor Angela Merkel's decision to accept nearly 900,000 migrants last year.
A leaked police document revealed the bulk of the crimes were committed in Cologne and Hamburg where 600 and 400 sexual assaults on women were reported respectively.
Authorities have therefore increased police presence at hotspots in the major cities, including Cologne.

The string of robberies and sexual assaults last year were blamed largely on migrants from North Africa and prompted nationwide outrage.
The tone of public debate in Germany has become shriller over the past two years with the influx of hundreds of thousands of migrants.
Some Germans blame Chancellor Angela Merkel for attacks such as the recent rampage in Berlin, where a failed asylum-seeker from Tunisia rammed a truck into a crowded Christmas market, killing 12 people and injuring dozens more.
The German capital has beefed up security after the December 19 carnage, deploying hundreds more police, some armed with machine-guns.
