Six shells of bullets have been found by the judicial panel members appointed by the Lagos State Government to investigate police abuses and the shooting at the Lekki toll gate.
The shells were recovered at the scene of the incident when the panel visited there on Friday.
The Nigerian Army, accused of carrying out the attack believed to have killed at least two people, had initially denied its troops were at the scene.
It later admitted soldiers were there on the invitation of the state government, but insists they shot no one, despite video evidence showing otherwise.
The bullet shells, found during an inspection of the Lekki site by the panel led by Dorris Okuwobi, would be expected to serve as critical evidence to establishing the truth.
The shells were recovered in the presence of journalists and the inspection was done alongside representatives of the Lekki Concession Company.
However, when Abayomi Omoruwa and Gbolahan Agboluaje, appeared before the judicial panel on Friday to present the CCTV footage recovered following the shooting, the panel did refused to receive the CCTV footage. It said the main assignment for the Friday was to visit the incident site.
But when they got to the Military Hospital where they paid an unscheduled visit to inspect the facilities and visit the morgue, they were refused entry by military men.
The panel which was led by the chairman was seen on live TV being denied entry after waiting for a long time. They left without any senior officer explaining why they were not allowed in.
