In the early morning hours of July 23, 1987, Argov, his brother, and another man entered the Magen David Adom station in Rishon LeZion and demanded drugs. Shortly afterward, Argov was arrested on suspicion of stealing the purse of a doctor in the area, but was released after it was determined he had nothing to do with the theft. During his release from the police station, Argov stole a pistol that was lying on a desk. After an extensive manhunt, he was arrested with the pistol in his possession, convicted, and sentenced to one month in prison, which was extended to six months upon appeal.
