On January 6, Apink was supposed to attend the opening ceremony of a Hi-Mart and hold a signing for their fans, but the event received a threatening call telling them of explosives allegedly installed at the venue.
The police were dispatched to the scene and evacuated customers and fans from the premises. The place was temporarily closed as they searched the area.
Apink was reportedly on their way to the venue and was diverted back to Seoul upon hearing about the incident.
The threat was assumed to have come from the blackmailer who has plagued Apink since last year and made several false reports and bomb threats since June.
The threats led to a number of their appearances being canceled with Eunji expressing her frustrations about it.
The individual responsible for the past bomb threats was identified as a man in his 30s living in Canada. The police requested the help of Interpol to locate him but there have been no reports of any progress made.
