Dramatic moment man, 19, is pinned to the ground by police outside Leeds bus station as officers shout 'you've got a knife'

This is the dramatic moment a 'knife-wielding' 19-year-old man was pinned to the floor and arrested outside Leeds bus station today.

Startled onlookers gathered at the scene as two officers held the man down and screamed "you've got a knife on you." The man appears to deny that he has the weapon before he is heard allegedly telling officers: "I can't breathe".

The video was filmed by Louis Kasatkin who was on his way to catch a bus in the city centre shortly before 12.30pm. He said: "I was approaching the bus station, about five minutes before my bus was due to depart, when I heard a commotion and saw a police officer taking up a "shooting stance".
