Police have arrested a 15-year-old boy in connection with the stabbing to death of a teenager in Liverpool, Merseyside police said on Sunday.
Police were called to an address in the Old Swan district of Liverpool early on Saturday morning where they found 16-year-old Luke Howard had been stabbed. He later died in hospital.
"It appears that this incident took place following an argument at a party at this property," said Superintendent Graham Yip.
"We are appealing for anyone who was at the address during the course of this party, to come forward and make contact with police."
