A 38-year-old Nigerian man was arrested for allegedly killing his mother-in-law after she discovered that he raped his wife's teenage sister.

The man, identified as Jimoh Jogbo, also killed another victim who saw him commit the crime, officials said.

The killings took place in the Akodo area in Ibeju Lekki Local Government Area, according to Sahara Reporters.

The Lagos State Police Public Relations Officer, Benjamin Hundeyin, confirmed in a Saturday tweet that Jogbo is in custody for the crimes.

Jogbo reportedly killed his mother-in-law inside a church after it came to light that he raped her 14-year-old daughter, who is also the sister of the suspect's wife.

"Preliminary investigation shows that he killed his MIL because she discovered he was having carnal knowledge of his wife's 14-year old younger sister (MIL's daughter) and vowed to take it up," Hundeyin wrote on Twitter.

Jogbo also killed another man who was a witness to the mother-in-law's murder, authorities said.

Jogbo's wife spoke to Punch and said her husband raped her younger sister on Nov. 6.

"That very night, my husband and I were outside around 11 p.m. but as he was talking to someone, I left him and went inside," she told the outlet. "He later came to sleep beside me. It was the following day that my younger sister told me he raped her at midnight. When I confronted him, he denied. I informed my mum and we became furious and asked him to leave the house."

Jogbo reportedly followed his mother-in-law to church on Nov. 14 and killed her.

A man named Durodola Agunloye said he found the slain woman's body at the church premises at around 2 a.m.

"I rushed out, went straight into the church and saw her in a pool of blood," Agunloye said. "She could not talk when I called her name but was only grasping for breath. Immediately, I alerted the chairman of our church, who came around with his car which we used in conveying her to the hospital where she was confirmed dead."

"We also reached out to some local vigilantes to mount surveillance in the community and Jogbo was caught while trying to escape. When they brought him to the church, he denied the killing," Agunloye said.

The second deceased victim was identified as Shakiru Jamiu.

"Around 7 a.m., we saw the corpse of a young man a few meters away from the church and we discovered that it was Jogbo's friend, Shakiru ... He attacked him with a stick and killed him. Jogbo used the same stick to kill his mother-in-law," Agunloye added.

Hundeyin said the case was transferred to the State Criminal Investigation Department for further investigation.
