Mr Pyke had lived in Nottingham for two years
A man arrested by police in Germany on suspicion of the murder of an internet gaming enthusiast in Nottingham is facing extradition proceedings.
Matthew Pyke, 20, was found stabbed in his flat above the Orange Tree pub on North Sherwood Street on Friday.
A 21-year-old man from Limburg was arrested on Wednesday in Hunfelden by officers from West-Hessen Police.
Nottinghamshire Police said the man, who has not been named, was now in Frankfurt for the extradition hearing.
A force spokeswoman added: "We are questioning him with German police."
Officers in England and Germany said the arrested man knew the victim through an online games forum.
Mr Pyke, originally from Stowmarket in Suffolk, ran a web forum for the Nintendo game Advance Wars on which gamers could chat online with each other about tactics, characters and plots.
He had lived in the city for two years and was about to start a degree at Nottingham Trent University.
In a statement released through Nottinghamshire Police on Thursday, a spokesman for the German force said: "Limburg-Weilburg police have arrested a 21-year-old man from the rural district of Limburg on suspicion of murder.
"He was arrested by officers from the West-Hessen police headquarters in Hunfelden on suspicion that on 19 September he killed a man in Nottingham with a knife.
"They got to know each other through the internet.
"The man has been extensively interviewed by Limburg CID at the petition of the public prosecutor."
Officers said the joint investigation between Nottinghamshire Police and the German force was still continuing.
