Man jailed for flatmate's murder in Manchester
A man who admitted murdering his flatmate in Manchester has been jailed.
Janusz Stanislaw Kosik, 57, stabbed Radoslaw Waclawiak in the chest after a row at the flat they shared in Crumpsall, Manchester, in September.
Police said Kosik had several disagreements with the victim and the two other men who shared the flat in Martingale Court before the killing.
He was ordered to serve a life sentence with a minimum term of 21 years during the hearing at Manchester Crown Court.
Police said in the weeks leading up to the murder, Kosik had thrown a glass at Mr Waclawiak which smashed against the wall in their flat.
He also threatened Mr Waclawiak, 25, and the other two men with a hammer.
On 21 September last year, all four men were drinking at the flat but Kosik spent most of the evening in his bedroom and complained about the volume of the television.
Later that night, he walked into one of the bedrooms and stabbed Mr Waclawiak with a large kitchen knife.
Police said he slashed him in the face and stabbed him in the chest before leaving the flat.
He was arrested three days later.
Speaking after sentencing on Tuesday Senior Investigating Officer Harry Harrison said: "Radoslaw came to England to make a better life for himself and instead was tragically killed by a man living under the same roof.
"The three men were kind enough to invite Kosik into their home and he viciously attacked and killed Radoslaw.
"Today's result should provide some solace for Radoslaw's friends and family and will hopefully provide some basis for them to move forward in their lives without him."
