Police on Wednesday fired teargas at the Lekki tollgate to disperse protesters.
This led to some of the protesters running helter-skelter.
The youths had converged on the Lekki tollgate to mark the first anniversary of #EndSARS in the country.
Speaking to journalists shortly after, Hakeem Odumosu, Lagos commissioner of police, said the protesters told him they were going to end the demonstration by 10 am.
Odumosu said any protest beyond the agreed time is constituting a nuisance.
“Between 8 am and 10 am, anything, after 10 am, is a nuisance,” Odumosu said.
“I discussed with them and they said they will end the protest by 10 o’clock. Any other person doing it now… that’s nuisance…. that have guns, the ones with machete, hammer, are they protesters or miscreants?
“The protesters are free; they have done their thing and left. Any other person remaining are the miscreants, hoodlums that want to capitalise on that to attack innocent people and start robbing people. We will not allow that.”
The CP also confirmed the arrest of a journalist and said he has ordered his release.
Earlier, operatives of the Lagos State Police Command arrested two protesters.
One of those arrested claimed to be a journalist while the other was seen carrying a placard.
About 30 police trucks and armed personnel are currently at the tollgate to enforce a ban on protests issued by the police command.
