Teachers Service Commission county director James Nkoroi has sent officers to Kongasisi Primary School to probe allegations of corporal punishment.
Parents of two pupils have accused the head teacher Josephat Njeru of injuring their children.
One of the pupils, who is in Standard Seven and is still nursing an injured arm, says he was beaten in January 2017.
The other one, a Standard Three pupil, was allegedly beaten before schools closed for August holidays.
The Standard Seven pupil underwent surgery at Kijabe Mission Hospital at a cost of Sh130, 000.
“I took my son to Kijabe because I had no otherwise and his condition was deteriorating every day,’ said the mother.
The standard seven pupil goes to the mission hospital for check after every two months at a cost of Sh5,000. Further, he undergoes physiotherapy at Nakuru Nursing Home weekly at a cost of Sh1,500.
