A trailer was set ablaze by unknown people along the Southern Bypass. This follows fresh demos called by Opposition chief Raila Odinga.
The trailer is yet to be identified, and so far, no casualties have been reported.
The motive behind the trailer being set ablaze is unknown.
Earlier today, goons attacked and burnt a bus along Ngong Road, Nairobi
Police used teargas to disperse the group that had gathered on the road in a bid to restore calm.
Some youths at the scene said those behind the attack are not from the area.
They said the attackers arrived in groups and looked organized. They then threw petrol bombs they had onto an oncoming bus as the driver tried to turn and escape in vain.
The Orange Democratic Party has, however, advised its supporters not to fall for alleged antics portraying the opposition as violent, insisting that the team has had peaceful demos.
"Our members and supporters and the entire Azimio la Umoja One Kenya Coalition family is hereby advised not to fall for the barefaced antics. We know their tricks and with time they will be ashamed," the statement read.
