Berlin police are appealing for information after a 26-year-old woman was kicked down a set of subway stairs by a man in Berlin, Germany, in October.
Lady Gaga and Charlize Theron’s bodyguard Michael Kuehr, 54, has offered a €2,000 (approximately £1,677) reward for anyone who can help identify the suspect and his apparent accomplices.
Kuehr was said to be so shocked by what he saw on CCTV that he wanted to help the authorities, who were struggling to find witnesses in an appeal.
He offered the money in a bid to bring the thug and his three thug friends – who watched the attack and did nothing – to justice.
Authorities have now detained a suspect in relation to the assault.
