The firm that manages the toll gate in Lagos, where protesters were shot at on Tuesday night, has said surveillance cameras mounted at the facility are still intact.

There had been allegations that the CCTV cameras at the Lekki toll gate had been removed.

In a statement, the Lekki Concession Company Limited (LCC) said that the street lights at the toll gate were off during the incident because of a power outage.

There were no staff to turn on the stand-by power generator as they had left in compliance with a round-the-clock curfew imposed by the state governor, it said.

It is unclear if the surveillance cameras were affected by the power outage.

The firm said it had not received instructions "from anyone" to dismount the surveillance cameras.

"Removing them will require the use of machinery to reach the heights that they have been installed and are still installed," it said.

Some protesters had said that the cameras were removed so that the shooting would not be recorded.

Amnesty International have said that 12 people died on Tuesday in Lagos. The army has said it was not behind the shooting.
