A police officer whose Nazi-themed tattoo could be seen in photos on social media is under investigation, Philadelphia police said Thursday. Activists on social media circulated a picture Wednesday night they said showed Officer Ian Hans Lichtermann’s left forearm tattoo of a Nazi Eagle with the word “Fatherland” written above it. His other arm displayed an assault rifle over a background of an American flag. Philadelphia police announced its internal affairs unit was reviewing the picture, though the department doesn’t have a tattoo policy. The Facebook user who posted the image of the officer said it came from a July 26 protest march during the Democratic National Convention. “The idea of being stopped, questioned, arrested, or of even passing this Officer on the street, Nazi insignias inscribed on his body with needle and gun, tattoo in plain sight, in a dominant placement on his body, is, in its most literal and modern sense, terrifying,” said the Facebook user, Evan Parish Matthews.
