Police in Kuria West arrested a young woman following the death of a 59-year-old man at local lodging.
The two, who have been in an illicit affair since 2013, are said to have checked in at the lodging in Ntimaru town where the man allegedly took some sex-enhancing drugs to boost his libido.
The man fell ill after the woman allegedly refused to sleep with him on grounds that she was menstruating, The Star reports.
He started groaning and turning on the bed with foam oozing from his mouth, according to Ntimaru OCPD John Losia.
"It was at this point that the woman rushed to the bar and lodging owner and reported the matter," Losia said on Tuesday.
The man was rushed to Mother and Child Health Centre where he was pronounced dead on arrival.
She was held at Ntimaru police station where she recorded a statement together with the lodging’s owner.
The woman told police that she declined to take the sex pills because she was unwell and only ate bread and a soda which the deceased had bought for her.
Losia said the matter is under investigation as they await post-mortem examination to establish the cause of the man’s death.
