STORY: This secluded forest is a temporary refuge for Kenyan activist Bill Eugene Omollo after what he describes as a traumatic ordeal.

Last month, he says, he was abducted by unknown men after taking part in anti-government protests.

"I was told to sit down forcefully. Once I sat down, it was a cold floor. They asked me to remove my pants, my tracksuit, so I removed my track suit. They even took my shoes off from me, they took my shirt off from me."

Human rights groups say dozens of Kenyans have been targeted in similar abductions in the past two weeks.

They blame the extrajudicial arrests on Kenya's intelligence services.

A police spokesperson did not respond to a request for comment on the abductions.

Nor did Noordin Haji, the director of Kenya's intelligence services.

In an interview on Sunday (June 30), President William Ruto denied police involvement in disappearances and broadly defended the actions of the security forces.

However Irungu Houghton, executive director at Amnesty International Kenya, said what they've seen is a number of "very disturbing patterns".

"It also has not begun to develop this pattern that we have not seen probably at this scale since the 1980s where people were considered to be protesters or organizers, or even just simply voices of dissent, being plucked from their homes, or even as they go to church with their family."

The protests, initially sparked by $2.7 billion in tax hikes, have developed into a broad movement that poses the biggest threat to Ruto's two-year-old presidency.

Though Ruto withdrew the proposed tax increases, an allegedly heavy-handed reaction has raised fears of rights backsliding.

For Omollo, he describes being taken just for demanding his rights as "so unlawful".

"It's against the constitution and I feel like the people that are doing this are supposed to be held accountable."

After 24 hours, Omollo's abductors, he says, loaded him back into their vehicle and left him near a police station.

He's now left Nairobi, worried that he is being followed and could be abducted again.

But he's also one of the lucky ones.

Rights groups say a handful of abduction victims remain unaccounted for.
