Police investigating how a 15-year-old boy fell from a bridge at a shopping centre have said they are treating it as an accident.
The teenager remains in a critical condition in hospital after falling from the covered walkway at the Trafford Centre in Manchester on Saturday evening.
Greater Manchester Police said five 15-year-old boys were arrested on suspicion of assault but had been released with no further action.
Initial enquiries suggested the boy may have been involved in an altercation with a group of youths but detectives no longer believe any crimes occurred.
Detective Sergeant Stephen Warriner said: "We have trawled through all the CCTV that showed this tragic incident take place and after speaking to a group of boys who were there at the time, as well as other witnesses, we no longer believe anything untoward happened.
"Sadly this seems to be a heartbreaking accident where someone's son is now fighting for their life in hospital.
"I want to thank the public for their help during this investigation and we will continue to focus our efforts on the family, providing them with support through this ordeal."
