Police on Wednesday briefly held a Kamiti Prison officer for questioning.
He was found with four guns in his house minutes after four Somali men drove into the prison to visit him.
The guns were found in the warder’s house as word went round that an attempt by al Shabaab to rescue their colleagues from the prison had been thwarted.
The warder has been attached to the prison for one year.
The four visitors are said to have been dressed in AP uniforms.
They visited the warder and left the guns in his house.
Kamiti Secondary School students were released from school early on Thursday afternoon under unclear circumstances.
Kasarani DCIO Valeria Obore yesterday said police were not aware of the incident.
Kenya Prisons Service commissioner Isaiah Osugo said the four men were AP officers attached to Dagoretti.
He said they went to the prison to visit the inspector, who is their relative, and left their guns in his house.
“The matter was investigated and resolved,” Osugo said.
The four allegedly drove in before the sentry confirmed they should be allowed in.
Suspicious prison warders alerted authorities and detectives were instructed to raid the inspector’s house.
