STAMFORD, Conn. (AP) Stamford police have arrested a third suspect in a fatal stabbing that police say began as a fight over spilled coffee.

Police arrested a 17-year-old Stamford resident Wednesday and charged him with hindering prosecution. The Stamford Advocate reports that police say videotape shows the teen carrying undisclosed evidence from the scene. He's set to be arraigned in juvenile court Thursday.

Antonio Muralles, who police say bumped into a 15-year-old boy outside a McDonald's on March 11, spilled coffee on the youngster.

Police say the 15-year-old boy and another suspect, James McLamb, punched Muralles. The teen is accused of fatally stabbing him.

The 22-year-old McLamb and the youngster have been charged with murder and each is held in lieu of $2 million bond.

Police say they have not recovered the knife.
