"The reports are currently being investigated to ensure the safety of schools and local communities."

Chief Inspector Chris Boyd of GMP's City of Manchester Division, said: "We take reports of this nature very seriously and whilst we have not advised any schools to close, our officers will nevertheless be stepping up their high-visibility presence around schools over the next few days to provide reassurance to them and the wider public."
