A 24-year-old man arrested on April 9 on suspicion of arson with intent to endanger life was initially released under investigation pending further enquiries. He has now been released with no further action.
Lancashire Police confirmed officers aren't looking for anyone else in connection with the investigation and "there is no evidence to suggest the cause of the fire is suspicious".
The incident was described as an "explosion" by Matthew Brown, leader of Preston City Council. Images from the scene showed charred walls, smashed windows and smoke damage.
A joint investigation between police and the fire service is underway with the investigation into the cause of the fire ongoing.
Detective Chief Inspector Graham Hill of the Force Major Investigation Team said: "This remains a very sad and tragic incident and my thoughts remain with all those involved at this time. While we initially did make an arrest we can confirm this man has been released no further action.
"He has been eliminated from our enquiries and we are not currently looking for anybody else in connection with the investigation. Our enquiries into the cause of the fire are continuing, however, at this stage of the investigation there is no evidence to suggest the cause of the fire is suspicious.
"I would urge people not to speculate and we will update you in due course." Anybody with information is asked to get in touch on 101 quoting log 1305 of April 8.
