A 32-year-old man implicated in a stabbing that left two people dead has given himself up at a police station in the Hamburg district where the killing occurred, officials said on Saturday.

The knife attack took place in the Billstedt district of the northern German city on Friday at noon, following an argument between the suspect and the two victims, men aged 58 and 61, police said. 

Police said the victims were the uncle and the father of the suspected killer.

They said the suspect would be put into pre-trial detention after preliminary police procedures had been carried out.

As part of the hunt for the killer, state prosecutors ordered searches of apartments in the districts of Lohbrügge and Horn on Friday evening.
