A state-owned newspaper in the United Arab Emirates is reporting that an alleged sexual assault caused a Dubai police officer to fatally shoot his colleague.

The National of Abu Dhabi says in its Tuesday edition that the accused, a 26-year-old Yemeni patrol sergeant, killed the 51-year-old Emirati armory officer after being handed his weapon at the start of his shift on Nov. 8.

The newspaper reported that Dubai Criminal Court heard testimony on Monday that the Yemeni officer accused the Emirati and another man of knocking him out with chemicals, then sexually assaulting him days earlier.

Violent crime is rare in the United Arab Emirates, a seven-state federation that includes Dubai.

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