Police are treating a fire at a mosque in Cheetham Hill on Sunday night as a hate crime.
The fire broke out just before midnight at the Al Falaha Mosque on Heywood Street.
Officers are appealing for eye witnesses and people with dashcam footage to come forward.
Detective Inspector Muz Kernain of GMP’s City of Manchester Division, said: “Fortunately, no-one was injured in the fire but had it been earlier in the day, this could have been a very different story.
“Attacking a place of worship is truly disgusting and I can assure you we will not be taking this lightly.
“It’s so important we find who has done this – the pain and upset they have caused is deplorable.”
Anyone with information should contact police on 101 quoting reference number 2220 of 09/12/18 or the independent charity Crimestoppers, anonymously, on 0800 555 111.
