A form four student was arrested on Monday evening in Ogembo, Kisii County over allegations of procuring an abortion so that she could sit the Kenya Certificate of Secondary Education (KCSE) exams.
It is alleged that the student whose identity could not be established immediately was six months pregnant.
"The foetus was found packed in a bag which she dumped in the nearby River Gucha. The suspect was arrested after a tip-off by a member of the public who discovered the foetus," said Kisii Police Commander Martin Kibet.
Mr Kibet noted that abortion is illegal in the country and urged women to accept and carry their pregnancies to term once they conceive to avoid deaths which may occur during or after abortion.
He also confirmed the arrest of three women suspected to have helped the schoolgirl to procure the abortion.
"Three women who helped her to procure the abortion are being held at Ogembo Police Station. They will be taken to court to be charged in accordance with the law once the probe is complete," he added.
The police boss warned women intending to help others procure abortions, saying the law will not spare anyone.
He further warned men against impregnating school girls saying such men belong in jail.
