The attack has gone viral since police last week shared CCTV footage, showing a man at Hermannstrasse U-Bahn station kicking a woman in the back, sending her tumbling down the stairs to land face-first on the platform below.
Berlin media report that the 26-year-old woman broke her arm during the fall.
The footage has been shared across social media and even been picked up by international press like Fox News and The Sun as police search for witnesses.
Though police have yet to identify the man responsible, they had received ten tips as of Monday, according to Tagesspiegel
And now at least two private citizens are getting in on the hunt. A former bodyguard to celebrities like Angelina Jolie and Leonardo DiCaprio, Michael Kuhr, wrote on Facebook on Sunday that he would pay a €2,000 “bounty” to anyone who could provide the name and address “of the bastard”.
“This makes my blood boil when I read this at breakfast,” Kuhr said in the message, along with a picture of him holding a newspaper about the attack.
An anonymous “prominent businessman” told tabloid BZ on Sunday
that he was willing to spend a total of €10,000 to help the victim and find the perpetrator.
“I will donate €5,000 to the victim so that she can go on vacation and recover from the pain,” said the man, who himself has a daughter. He also said he would pay €5,000 to the person who could correctly identify the man in the video.
According to Tagesspiegel, police said on Monday that they still do not have concrete leads on the perpetrator or his acquaintances, who are shown in the video standing by during the attack.
