The judicial panel set up by the Lagos State Government to investigate police abuses and the shooting at the Lekki toll gate has found bullet shells from the scene of the incident.
Officials confirmed six shells were found on Friday, 10 days after the shooting, according to Premium Times NG.
The Nigerian Army had initially denied its troops were at the scene when it was accused of carrying out the attack believed to have killed at least two people.
Amid wide condemnation of the shooting at the unarmed protesters, officials of the Nigerian Army later admitted soldiers were there on the invitation of the state government but insisted they shot no one, despite video evidence showing otherwise.
The bullet shells recovered in the presence of journalists during the inspection by the panel led by Doris Okuwobi would be expected to serve as key evidence as the probe of the matter progresses.
Also present during the inspection were representatives of the Lekki Concession Company Abayomi Omoruwa and Gbolahan Agboluaje.
Omowura and Agboluaje had earlier appeared before the panel on Friday to present the CCTV footage recovered following the shooting which was rejected.
