Police in Lagos State have arrested a 38-year old man for allegedly killing his mother-in-law and one other person after raping his wife’s teenage sister in the Ibeju-Lekki area of the state.

The Police Public Relations Officer (PPRO), SP Benjamin Hundeyin, confirmed the arrest in his verified Twitter handle monitored by newsmen.

He said that the suspect also killed the person who saw him perpetrating the act.

“The suspect killed his mother-in-law, only to discover someone saw him committing the crime.

“He quickly killed the man that saw him.

“Preliminary investigation shows that he killed his mother-in-law because she discovered he was having carnal knowledge of his wife’s 14-year old younger sister (mother-in law’s daughter) and vowed to take it up,” he said.

According to Hundeyin, the case has been transferred to the State Criminal Investigation Department (SCID) for conclusion of investigation and arraignment.
