A man, arrested by detectives investigating the death of a toddler in an explosion in Oldham, has been released on bail.
The 32-year-old from the Shaw area of the town, was held in London on Wednesday and was taken to Manchester for questioning in connection with Tuesday's massive blast which killed 2-year-old Jamie Heaton.
The suspect, who police say may have done some boiler maintenance work at one of the houses in Buckley Street, has been bailed until August 9 pending further inquiries.
Officers are also waiting to question the two-year-old's neighbour Andrew Partington, who was left with life-threatening burns after being caught up in the blast.
Detectives said the 27-year-old faces "significant questions" in the wake of initial police and fire service investigations and officers are at his bedside at Wythenshawe Hospital in Manchester waiting to be given the go-ahead by doctors to quiz him.
Greater Manchester Police said a murder inquiry may be launched following the deadly explosion which tore through three homes.
Steve Heywood, Assistant Chief Constable of Greater Manchester Police said detectives had information suggesting the toddler's death may not be accidental.
"We are treating it as a suspicious death and therefore a homicide investigation is undertaken."
