Five UoN students were arrested at a house in Lower Kabete on Tuesday morning on suspicion of being thugs.
Police found a gun, five bullets and bhang in the raid that followed a tip-off from neighbours.
The neighbours said the five, who had student IDs, had been arguing over the weapon.
UoN corporate communications director John Orindi told the Star on phone that they have received the reports from the police and are awaiting the outcome of investigations.
A neighbour who requested anonymity said he recognised one of the men as his classmate at the university’s Lower Kabete campus.
Kikuyu OCPD Birgen Kiptoo said: “We are holding them as we investigate cases of break-ins around the area.”
He said they will be arraigned in court once investigations are completed.
One of the suspects, identified only as Gitonga is a third-year, second-semester student of commerce.
His classmates said he goes to school regularly but is always drunk and sleeps during lectures.
They said the trend began shortly after he joined the campus.
“He was very humble as a freshman but he joined groups of alcoholics and drug dealers. I am no surprised he is now among thugs,” said one who did not want to be named.
The group is believed to be behind Monday night robberies in King’eero and Kabete.
