Mwangi took to Twitter to share a video of him when he encountered a car with number plate GKB 970R trailed by other two land cruisers and a police car with sirens on which was moving against the traffic in a wrong lane.

A bodyguard trying to persuade Mwangi was told off after claiming that Mwangi was on a wrong side.

"Who are this driving on the wrong side? I am not moving...you are the one on the wrong side.. no I am not moving.. Tabia Mbaya." activist Mwangi is heard on the video.

The bodyguard tried to knock Mwangi's car window but the defiant Mwangi was unshaken. The convoy proceeded with the journey driving on the same wrong lane.

Mwangi accompanied the video with a tweet saying that such people are endangering lives of road users. He further pointed out that the use of sirens must be only during an emergency.

"it's arrogance, endangering lives and breaking the law. I block anyone on the wrong side, the law is clear on use of sirens, it doesn't say "clearing traffic" EMERGENCY ONLY!" Reads part of Mwangi's tweet.
