The retired officer will be summoned on the basis of the revelations made by the Army intelligence officers presently in remand custody over their role in the incident.
Police sources say that soon after Noyarh was abducted, Maj. Prabhath Bulathwatte, who had led the abductors, informed Karunasekara about the incident.
Karunasekara in turn informed the then national intelligence chief Kapila Hendavitharana, who notified the then defence secretary Gotabhaya Rajapaksa, it has come to light by the analysis of telephone conversation data.
On the advice by the Attorney General’s Department, the CID has built up the circumstantial evidence.
Suspects presently under custody are Maj. Prabhath Bulathwatte, sergeants Duminda Weeraratne and Hemachandra Perera and corporals Lasantha Wimalaweerea and Nishantha Jayatilake.
The CID says they had operated from a safe-house located near Technical Junction in Colombo Pettah.
They had reported to Karunasekara, and the Army commander at the time was Sarath Fonseka.
Reports say Noyarh had been abducted and assaulted in order to know his sources for government defence news.
