Detectives are continuing to question the mother of a baby killed in a fire.
Four-month-old Alexander Gallon died in the fire
Four-month-old Alexander Gallon died in the blaze at a house in Cowgate, Newcastle, on Sunday night.
His mother Danielle Wails, 21, told police she was bound with telephone cord by two men who entered the house, attacked her and started the fire.
But Northumbria Police said on Thursday that they had suspended an appeal for two men initially sought in connection with the murder inquiry.
On Tuesday, another woman in her early 20s was arrested and bailed by police.
Police said that early indications following a post-mortem examination on the baby showed he had died as a result of the fire.
Further tests were being carried out.
