This was his third summons following investigations on January 23 and February 15.
On December 23 last year, police formally booked him on charges of violating the Military Service Act.
However, apart from this official statement, Song Min Ho has remained silent.
If the unauthorized absence exceeds eight days, he could face up to three years in prison.
He later re-enlisted as an active-duty soldier in 2007, fulfilling his mandatory military service for 20 months.
