Authorities in Dubai are holding a Yemeni member of the emirate's police force on suspicion of murder after he shot and killed another officer inside a police station.

Dubai police confirmed the Sunday shooting in postings to official social media accounts on Monday. Neither officer was identified, but police say the victim was also Yemeni.

Dubai's police chief, Maj. Gen. Khamis Mattar Al Mazeina, denied there was any political motive and said the shooting happened because of personal differences.

Violent crime is rare in the United Arab Emirates, a seven-state federation that includes Dubai. The Emirates and Saudi Arabia are leading a coalition of countries battling Iranian-backed Shiite rebels in Yemen.

Native Emiratis are far outnumbered by foreign guest workers, and some foreign nationals work in the country's security forces.
