Activists Boniface Mwangi took to Twitter on Monday to wish his Ugandan counterpart Dr Stella Nyanzi a happy birthday and called for her release from detention.
Sharing a picture of himself and the Ugandan activist, Mr Mwangi paid homage to Dr Nyanzi's courage and branded her an inspiration.
He then deployed hashtags calling for her release.
"Happy Birthday to the revolutionary Dr. Stella Nyanzi. Her courage in the face of state oppression is an inspiration to all of us. Detention hasn't silenced her. She keeps on writing and speaking truth to power from prison. Let's keep pushing for #FreeStellaNyanzi #PushforStellaNyanzi," Boniface Mwangi's tweet read.
Dr Nyanzi has been a strong critic of her government.
Her criticism and social media activism has seen her rub the government the wrong way and her spend time behind bars.
Both of them are birds of a feather in their blistering criticism of their respective governments.
Boniface Mwangi has on numerous occasions called out the Uhuru-led government for what he calls rampant corruption and bad governance in the country.
About a month ago, Boniface Mwangi was arrested over allegations that he was plotting a revolution.
He was later released after being subjected to interrogation by the Directorate of Criminal Investigations (DCI).
