Several students from a Machakos school were on Monday busted drunk as they travelled to attend a text book play in Ngara, Nairobi.
A teacher and the driver of the bus were also arrested in the Tuesday incident.
Police said the students were 'drunk as hell' after they contributed cash and bought several bottles of whiskey.
They were four girls and five boys.
An alcoblow test showed the nine had taken high levels of alcohol, a police source said.
They were arraigned at the Milimani Law Courts in Nairobi but did not take plea.
They are expected to appear in the children’s court on Wednesday, June, 13.
