The Mayor of Cologne said today that women should adopt a “code of conduct” to prevent future assault at a crisis meeting following the sexual attack of women by 1000 men on New Year’s eve.

Mayor Henriette Reker attended an emergency meeting with Chief of Police Wolfgang Albers and Wolfgang Wurm to discuss how to deal with the attack, where dozens of women were repeatedly touched and groped, with one case of alleged rape in the center of town.

“It is important to prevent such incidents from ever happening again,” said Mayor Reker, as reported in German by RP Online. “We have heard by now that they [the attacks] have occurred in other cities. This of course is not comforting to us.”

Hamburg also received complaints of sexual assault.
