Ailey was taken to the Arlington Jail and released Sunday night on a $1,000 bond, Miller said.
Ailey, a Dallas police officer for 23 years, was arrested in December on a DWI charge. He was placed on administrative leave after that arrest and then assigned to the communications division, Dallas police spokesman Sr. Cpl. Kevin Janse said.
He is again on paid leave since his arrest Sunday, Janse said. Ailey did not immediately respond to a message left Monday by The Associated Press.
