There was tension on Wednesday around the Federal Road Safety Corps (FRSC) office in the Ojodu area of Lagos.
This comes a day after a trailer rammed into some students at the Grammar School bus stop, killing some of them.
There are fears of violence breaking out in the area.
Earlier in the day, Channels TV also observed that the police had cordoned off a filling station just meters away from the scene of the incident.
Commercial activities within the vicinity also appeared to have been shut down.
The incident occurred at Grammar School Bus-Stop along the Ogunusi Road on Tuesday afternoon when schoolchildren were returning to their respective homes.

The Commissioner of Police in the state, Hakeem Odumosu, confirmed the incident to Channels Television via a telephone interview.
Although he said two students died with others injured, eyewitnesses at the scene gave conflicting accounts.
While some claimed about 13 students were feared dead, others said 17 schoolchildren died.
They were said to have been crushed while waiting to cross to the other side of the road.
According to the police commissioner, the truck driver had attempted to escape after hitting the schoolchildren.
But he was later arrested by operatives attached to the Divisional Police Headquarters in Ojodu who chased him after he fled the scene.
