Greater Manchester Police (GMP) said there were 224 reports of anti-Muslim hate crimes in the month after the attack at an Ariana Grande concert at Manchester Arena compared with 37 in the same period in 2016.
This marks a 505 per cent rise in Islamophobic incidents as officers said they would take tough action to curb the increase in hate crimes.
"Greater Manchester has a diverse population, with people from different faiths and backgrounds, and this is something that we are proud of. It's what makes us the city we are. We will not tolerate hatred or discrimination of any kind," said Rob Potts, assistant chief constable of GMP.
"When a major tragedy occurs such as the attacks in Manchester and London, it is sadly not unusual for there to be a spike in the amount of hate crimes, specifically against race and religion, but thankfully they do decrease again quickly," he said.
Race hate crimes have jumped 61 per cent, to 778 incidents, compared with the same four weeks last year.
There is no official breakdown about the nature of the incidents but local businesses, mosques leaders and individuals have spoken about physical and verbal abuse.
