A veteran Dallas police officer was arrested early Sunday, for the second time in three months, on suspicion of driving while intoxicated.

Senior Cpl. Billy Ailey was stopped about 3:30 a.m. on eastbound Interstate 30 near State Highway 360 and refused a breath test, an Arlington police spokesman said. Authorities got a warrant and took a blood sample at a hospital. Cpl. Ailey was later released on bond.

Dallas police said he is on administrative leave pending an internal-affairs investigation. Cpl. Ailey is assigned to the police communications division and has been with the department since January 1985. Cedar Hill police arrested him on a DWI charge in December.
