Authorities in the Dominican Republic say a policeman has been shot to death by a fellow officer in apparent dispute over use of a cash machine on payday.

Preliminary police reports say Lt. Bernardo Montero is dead from a bullet allegedly fired by Sgt. Yuder de los Santo during a heated argument Tuesday at a bank ATM. The sergeant was wounded.

Some witnesses report that the dispute started when Montero bypassed a line of customers at Banreservas. That is a state bank where police, military and other public employees receive their wages.

Police Chief Jose Armando Polanco has ordered a special investigation to determine exactly what happened.
