MARAWI, Lanao Del Sur - ABS-CBN News on Thursday obtained CCTV footage of terrorists surrounding a police officer here, moments before he was shot dead last May 23. 

In the video taken from Amai Pakpak Hospital, black-clad men carrying high-powered firearms are seen entering the premises of the hospital, with one suspected Maute member taking the gun of the security guard. 

Senior Insp. Freddie Solar is then shown surrounded by the gunmen, who order him to drop to his knees. 

Solar later walked inside the hospital with his arms raised.

Solar's wife earlier said the militants forced the cop to his knees and pray like they do before killing him. 

The CCTV footage provided by an ABS-CBN source was taken on the day that Maute and Abu Sayyaf fighters launched their siege of Marawi City, which prompted President Rodrigo Duterte to place all of Mindanao under martial rule. 

The fighting in Marawi has left dead 134 Maute fighters, 39 state troops and 20 civilians as of Thursday morning, according to military spokesman Brig. Gen. Restituto Padilla.
