Overview

• On Monday at U-Bahnhof Museumsinsel two fare inspectors detained a 21-year-old woman for riding without a ticket and her fiancé arrived and threatened them with a folding knife
• The woman’s 46-year-old father, wearing his police uniform, intervened by identifying himself as an officer and escorting the couple away
• Arriving officers found no knife at the scene and both the woman and one inspector reported arm pain but declined medical treatment
• Berlin police have opened formal probes into the 21-year-old on charges of robbery-like extortion and mutual assault and into the father for impersonating authority
• The case highlights growing safety concerns over violent confrontations during routine transport fare inspections
