Detectives and fire investigators have this morning returned to Manchester Dogs’ Home to establish the cause of last night's fire..

The death toll now stands at 53 dogs overnight with more than 100 rescued from the fire.

Today experts were sent back to the scene to speak to witnesses and trawl through evidence in the damaged building.

A fire service spokesman said the team will try to find the exact point where the flames first took hold.

Police confirmed that a 15-year-old boy was held last night on suspicion of arson and will be quizzed today.

Four crews were called to the scene at 7.20pm and extinguished the flames, which claimed the lives of at least 53 dogs.
