And once again, THE SUN, has news that no one else reports first, just like the last several events in England.
So
The Sun is reporting this person screamed, they want to "kill all Muslims." They are also saying bystanders tackled the 48 year old man. So if The Sun is correct, again, we may have found out the source of all this. Granted they say Buzzfeed is the source of that quote... and Buzzfeed is the queen of FAKE NEWS... so take this with a grain of salt.
Some nut job sicko trying to "make things right" by killing people of a certain group for no reason other then they are of the religion of the terrorists.
