Police in the city of Tulsa in the U.S. state of Oklahoma have arrested two suspects in the shooting death of three African Americans.

CNN and other U.S. media report that a city-federal task force arrested and is investigating 19-year-old Jake England and 32-year-old Alvin Watts. The shooting rampage took place on Sunday. Two other people were wounded in the incident.

Tulsa Mayor Dewey Bartlett said many reports came in through the anticrime network set up by local residents, which led to the arrest of the suspects who were hiding at home.

Both of the suspects are white, but police and the FBI say it's too soon to say if the attacks were racially motivated.
