Police previously said they were looking for a man in a white truck.
The Rev. Warren Blakney Sr., president of the Tulsa NAACP, said the arrests came as a big relief. Black community leaders had met Friday night amid fear over the shootings and concerns about possible vigilantism in retaliation.
“The community once again can go about its business without fear of there being a shooter on the streets on today, on Easter morning,” Blakney said.
It was not immediately known if the suspects had lawyers.
Police Chief Chuck Jordan said the gunmen appeared to have chosen their victims at random. Police identified those killed as Dannaer Fields, 49, Bobby Clark, 54, and William Allen, 31. Two men were wounded but were released from the hospital, Jordan said.
The shootings come at a fraught moment for black Americans. In late February, an unarmed black teen, Trayvon Martin, was fatally shot by a neighborhood watch volunteer in Sanford, Fla., raising questions about racial profiling and touching off protests across the nation.
While Tulsa police were reluctant to describe the shootings there as racially motivated, City Councilman Jack Henderson was not.
“Being an NAACP president for seven years, I think that somebody that committed these crimes were very upset with black people,” Henderson said. “That person happened to be a white person, the people they happened to kill and shoot are black people. That fits the bill for me.”
