A 56-year-old Wajir man is on the run after his son was allegedly struck in the head and died.
Abdulahi Ibrahim Mohamed, 18, was pronounced dead on arrival at Wajir County Hospital on Tuesday. Police said he had head injuries.
The young man had been referred from Gastekoftu Health Centre more than 20km away.
Police visited the home of the victim and established the teenager had been beaten on the head with a club.
The motive was not known.
The body was photographed and handed over to the family for burial according to Islamic rites.
Northeastern police boss George Seda said they are looking for a known suspect.
Domestic violence is on the rise in the drought-stricken region.
Meanwhile, tension is rising in Merti, Isiolo county, after a herder was fatally shot in an attempted cattle theft.
Gole Diba Tari, aged 46, was killed during skirmishes between two communities.
Retaliation was feared. Police said no arrest has been made but teams are pursuing suspects.
Cattle rustling is persistent in the area.
A security operation is underway in the area but the dusk to dawn curfew was lifted.
The operation is now targeting illegal guns. Officials said the operation would continue until at least 5,000 illegal guns are recovered.
In June, officials said although the multi-agency team deployed in May had restored peace, seizing illegal weapons must be concluded in a long-term security strategy.
Only about 300 guns, 3,000 rounds of ammunition, a grenade and assorted bayonets have been surrendered or recovered under Operation Rejesha Amani.
The officers are drawn from the General Service Unit, Anti-Stock Theft Unit, Rapid Deployment Unit and others.
