A senior police officer based in Turkana Central was arrested and released on cash bail pending arraignment over the assault of Capital FM journalist Angela Muiruri.
The assault incident happened on December 19, 2020, at a residence in Kileleshwa, Nairobi.
Police based at the Internal Affairs Unit arrested the Senior Superintendent of Police after he honoured the summons and appeared before them on Tuesday.
He was later taken to Capital Hill police station where he was processed and further released on police cash bail of Sh40,000 ahead of the planned plea taking on December 6, police said.
The move follows the directive by the Director of Public Prosecutions for police to charge Boit with assault.
There have been futile efforts to reconcile the two.
IAU established that the police boss, applied excessive force on the radio presenter, warranting him to be charged with two counts of assault causing actual bodily harm, contrary to section 251 of the Penal Code.
At the time of the incident, he was the officer in charge of the operations to ensure compliance with Covid-19 regulations.
Angela was among 21 women who were assaulted during a security operation in Nairobi's Kileleshwa estate at the height of the COVID-19 pandemic.
At the time, Angela, a former Miss Kenya-USA pageant winner, said they were about to leave a garden party when more than ten police officers stormed in and ordered everyone to sit.
When she questioned the police's actions, she was slapped and was left nursing injuries.
The other women were also whipped, and all were detained in the parking lot way past curfew hours.
"As a citizen, I understand my rights and I say you cannot manhandle women like that. I think that made the officer mad, and as I was saying that I was slapped, but I tapped back at the officer, and that is when he proceeded to whip me," she said.
The women were then bundled into a waiting police lorry and driven to Muthangari police station where they were booked and later released at 4am after parting with Sh1,000 each.
She later filed a formal complaint at the KICC Police station against the police boss, whom she had identified as the person behind her assault.
This was after attempts to report the matter to Kileleshwa, Kilimani, and Nairobi area police failed.
The report attached a medical report from a Nairobi hospital that showed she suffered severe bruises on her lower limb.
A clip showing what transpired went viral on the internet, sparking Kenyans' outrage.
