Pol Lt-Colonel Jakrarom Thoopjaem, who heads the station’s crime suppression division, allegedly shot Pol Colonel Thanatpong Prasertsiriprapa, who was pronounced dead in hospital later.
Provincial Police Region 6 chief Wanchai Thanatkij said the shooting had possibly resulted from Jakrarom’s drinking habits and stress from being constantly rebuked by Thanatpong.
Police arrested Jakrarom, who tried to flee after the shooting but ended up crashing his car into a tree and injuring himself.
Jakrarom was initially charged with killing a police officer on duty and dismissed from civil service.
Since Thanatpong died on duty, he was promoted to the post of police general posthumously and granted pay and pension raises, Wanchai said.
