Police in Cologne, Germany, have arrested a 52-year-old man who they suspect blew up his daughter's boyfriend. According to authorities, the man forced his way into the 17-year-old's apartment on Monday and poured gasoline on the floor. When the gasoline evaporated, it caused a huge explosion that sent the teen flying from a window on the building's fourth floor.

The boy died at the scene, while the suspect suffered injuries and is currently in a coma. Police believe the man may have previously threatened the boy because he was unhappy with the relationship he had with his daughter.
