Acting Interior CS Fred Matiang’i had banned protests in the CBD. Nasa defied the orders.
The Nairobi business community attacked Nasa leaders and hurled stones at their cars.
The National Super Alliance (Nasa) leaders and supporters on Friday engaged police in fierce confrontations during demonstrations against the electoral commission as Nairobi city centre remained under a lockdown.
Police shot in the air several times to disperse the group that at some point clashed with rival members of the Nairobi business community.
Police and Nasa supporters clashed along Moi Avenue and at the General Post Office as the protesters tried to force their way into the central business district.
All this while, the MPs, led by Siaya Senator James Orengo, Dagoretti North MP Simba Arati and other leaders, remained in their cars as supporters marched along the streets.
The protesters unsuccessfully tried to reach the Independent Electoral and Boundaries Commission (IEBC) offices at Anniversary Towers.
Earlier at the Nasa secretariat at Capitol Hill, Mr Orengo led the MPs in a press conference criticising the directive by acting Interior Cabinet Secretary Fred Matiang’i to ban the demonstrations from the CBD.
The MPs, who had mooted plans to sneak through the city centre while riding inside their cars, were forced to scamper after police lobbed teargas at the group.
