British detectives investigating the death of a baby in a house fire have arrested his mother in connection with the murder.
Alexander Gallon, aged four months, was killed in the blaze at the two-bedroom property in Cowgate, Newcastle, on Sunday night.
His mother, Danielle Wails, (21) has reportedly been arrested.
Northumbria Police said a 21-year-old Newcastle woman was being questioned on suspicion of murder but refused to give any more details.
Another woman, in her early 20s, was released on police bail after being questioned as part of the inquiry.
Ms Wails told police two men burst into her house, attacked her and tied her up, then fled after setting fire to the living room where the baby had been asleep.
Police, who appealed for help in tracing the attackers at a news conference, said they have found CCTV images of two men in the area shortly before the fire broke out.
A force spokeswoman said: "We have CCTV footage that shows two men at the corner of Link Road and Whitehorn Crescent at 10.30pm on Sunday.
Early indications from a post mortem showed Alexander died as a result of the fire, police said.
