Detectives are holding four Nigerian men in connection with the death of a 25-year-old man in the Riruta area, Nairobi.
The victim identified as Charles Waga Otieno is said to have jumped from the fifth floor of an apartment after an altercation with four Nigerians.
Waga was a budding rapper, his friends said.
The four were occupants of the house.
Police visited the scene and established the man had gone to deliver carpet at the said house on the seventh floor room 56 rented by a Nigerian who paid him Sh400 for the work.
The deceased was later heard screaming while stripping naked and jumped from the fifth floor to the ground floor where he sustained serious head injuries.
He was rushed to Coptic Hospital where he was pronounced dead on arrival, police said.
The four foreigners were arrested pending investigations into the incident.
Police said they are investigating a murder incident.
It is not clear what motivated the man to jump to his death while naked in the Monday afternoon incident.
The body was moved to the mortuary pending autopsy.
Meanwhile, police are investigating the death of a man whose body was on Tuesday found dumped next to a funeral home in Lari, Kiambu County.
Police said the body of Stephen Maina who was a driving school instructor in Lari Constituency was discovered by residents who later informed his family.
Maina's body was moved to the Up Home Mortuary, which is located right next to where the body was discovered, police said.
This is the second body discovered in days after yet another body of a middle-aged woman was found dumped in Kinale Forest on Monday.
She had reportedly been raped before she was killed. Police said the scene was secondary.
No arrest has been made so far but detectives are investigating the murder incidents.
Cases of homicide are on the rise in the area amid calls for justice.
