Garissa (Kenya) (AFP) - Police in Kenya said Monday they have launched an investigation into photos posted on social media that appear to show officers mercilessly whipping a group of young Somali men.
The pictures were posted on the Facebook page of Michael Orita, who sources say is a senior police official in Kenya's northeastern county of Garissa, the scene of the April massacre of nearly 150 students by Somalia-led Shebab rebels.
The victims were identified in the Facebook post as Somali men who had crossed the border into Garissa -- following the path of many from war-torn Somalia who travel to Kenya to seek casual labour.
"These Somalia young men came to Garissa for a purpose but little did they know we are smarter than them... we shall not relent on security issues," the post says.
The photos show a group of around 10 young men face down in the dirt while they are being whipped by what looks to be a rubber hose by a man in civilian clothes carrying an assault rifle.
Uniformed police look on and a marked police four-wheel drive is visible in the background.
Another picture appears to show another plain-clothed official trampling over the youths. The pictures were later pulled from the social networking site after an outcry over police brutality.
"How will the security agencies expect the local people to work with them while they torture people in this manner?" said Khalif Abdi, coordinator of the North-Eastern Forum for Democracy.
"What will stop the victims from harbouring resentment against their government and having a soft heart for terrorists?"
Local MP Abdikadir Ore said such incidents were the reason why Kenya's fight against Islamic extremism -- frequently blighted by allegations of police brutality and extrajudicial killings -- "cannot be won".
"This perhaps explains why the community has not been cooperating with security officers," he was quoted as saying by The Star newspaper.
- 'No way to fight terrorism' -
Garissa County police commander Shadarack Maithiay said an investigation was under way.
"The pictures have come to my attention and I have instructed the relevant agencies to speedily investigate their authenticity and whether the person claiming to be a senior police officer who posted them is a genuine member of our security force," he said.
Maithiay said he was unable to confirm if there was a Michael Orita in the local force.
But he added: "Even if we found we have such person in our force we can't conclusively say he is responsible without our investigation proving that."
"What is seen in the pictures is wrong. It is against the ethics and the code of conduct for any security force. I'm disturbed but it is good for us to be patient for our investigations to establish whether they are genuine," he said.
Quoted by The Star newspaper, Garissa County Commissioner James Kianda said those involved "will face disciplinary action, of course subject to validation."
"This is not how we want to fight terrorism," Kenya's national police chief Joseph Boinett was also quoted as saying.
Kenyan media reports said the pictures were believed to have been taken close to the village of Yumbis, about 80 kilometres (50 miles) northeast of Garissa town, and the scene of a recent ambush on police by Shebab militants.
The ambush, which left one officer dead, prompted a major security crackdown in the area.
Garissa County has remained volatile with numerous attacks since last month, when four Shebab militants stormed Garissa University College, killing 142 students and six members of the security forces during a day-long siege on the eve of the Easter weekend.
It was the group's deadliest attack in Kenya to date.
Once a Somalia-focused insurgent group, Shebab has in recent years turned its attention to Kenya, demanding it withdraw soldiers who were deployed to Somalia in 2011, and launching a series of attacks including the 2013 assault on Nairobi's Westgate mall that killed at least 67 people.
