Police said they caught on Thursday night the final person wanted in connection with the murder of policeman Sultan Al-Juaid who was killed in a shootout last Tuesday. The arrest, which brings to four the number of persons detained over the incident, was made at the suspect's home after he made a telephone call to his brother. According to police, the man had been dressed as a woman to evade the attention of authorities. Two other suspects previously handed themselves in on Thursday, the same day that the prime suspect, a 26-year-old man already in custody, confessed to the shooting. Private Al-Juaid, 22, was killed while on patrol duty when the prime suspect, who was wanted in connection with narcotics offenses, opened fire on his vehicle.
