There is an alarming trend in the Sri Lankan security forces operation, of arresting the family members of suspects and keeping them as hostages in detention camps. Irrespective of their age, gender and connection to those suspects, the family members are kept under arrest/ detention most notably in the infamous 4th/ 2nd floors in Fort and in Boosa Detention camp under the control of TID.
