Bonchari Member of Parliament John Oyioka has claimed that Interior Cabinet Secretary Fred Matiang'i is a liar.
Speaking at Suneka on Monday, the MP said that the CS had deceived locals that the police will ensure they arrest the persons who were involved in the abductions of Pastor Esther Bochaberi.
"A government official of his capacity should not give false hope especially to families that have lost their loved ones. Let him come out and tell us how far the investigations are," said Mr oyioka.
The MP accused Mr Matiang'i of issuing threats but being less productive.
Ms Bochaberi was buried last month after her lifeless body was found in Migori county, days after she disappeared from her home.
Mr Oyioka, promised to follow the matter up with the Kisii County commissioner.
"The family of the late pastor should ignore Matiang'i and ensure they use other means to get justice because police have failed to help. The killers are well known by police but no arrests have been made until today," he said.
