The Chinese man identified as Geng Quangrong, who was arrested in Kano for stabbing his Nigerian girlfriend, Ummu Kulthum, to death has opened up on why he committed the heinous crime.

Geng killed 23-year-old Ummu last Friday, September 16, in her home in Kabuga Quarters, Dorayi Babba area of Kano State.

He reportedly confessed to the crime after he was arrested by the police in Kano.

Geng, 47, said he killed Ummu because she promised to marry him but later reneged on that promise after he had spent so much money on her.

Geng has since been transferred to the state headquarters at Bompai for further investigation and prosecution.

Meanwhile, late Ummu was buried Saturday morning, September 17, in Kano.
