Narrative:

Aircraft Y landed on runway xx and exited at taxiway zz. Aircraft X was conducting a touch and go on runway xx. Ground control coordinated with me to cross runway yy with aircraft Y. I approved the runway crossing not realizing that aircraft X was on the go on runway yy. The controller in charge notified both ground control and myself; and ground tried to contact aircraft Y; but the ground frequency was busy from another aircraft. Closest proximity was approximately 1650' lateral and 200' vertical. Recommendation; perform an effective scan when coordinating runway crossings.

Title: Local Controller authorized Ground Controller to cross parallel runway without realizing conflicting touch and go traffic was on the go and still a factor.

Narrative: Aircraft Y landed on Runway XX and exited at Taxiway ZZ. Aircraft X was conducting a touch and go on Runway XX. Ground Control coordinated with me to cross Runway YY with Aircraft Y. I approved the runway crossing not realizing that Aircraft X was on the go on Runway YY. The CIC notified both Ground Control and myself; and Ground tried to contact Aircraft Y; but the ground frequency was busy from another aircraft. Closest proximity was approximately 1650' lateral and 200' vertical. Recommendation; perform an effective scan when coordinating runway crossings.
