Lawyer Ahmednasir Abdullahi has mocked Friday's arrest of Embakasi East MP Paul Ongili alias Babu Owino.
Owino was arrested in connection to a fatal shooting incident that left one person critically injured in Nairobi.
According to the DCI, investigations are currently ongoing to establish the motive of the incident that happened in a club.
"@DCI_Kenya Detectives based at Kilimani have today arrested Hon Paul Ongili alias Babu Owino, Member of Parliament for Embakasi East following a shooting incident at B Club located along Galana Road within Kilimani. The MP is in lawful custody as further investigations continue," DCI said in a tweet, Friday.
But Ahmednasir says Mr Owino should be released immediately, sarcastically saying that he's a proponent of Building Bridges Initiative (BBI).
"HOW can the POLICE arrest a HANDSHAKE/BBI MP? Babu Owino must be released...immediately," tweeted Ahmednasir.
In recent weeks, Ahmednasir has poked holes into the arrest of DP William Ruto's allies, with the incarceration of Gatundu South MP Moses Kuria last week angering him.
Mr Owino on Thursday said opposition leader Raila Odinga will be president come 2022 either "through ballot or bullet".
It's not the first time the MP is being arrested. In 2017, he was arrested by the police for allegedly abusing President Uhuru Kenyatta.
