The Daily Star said a witness on Twitter suggested a female "cyclist was stabbed in the back," as well as another person, but that is an unofficial report and has yet to be confirmed by authorities.

Others have said a man stabbed the cyclist with "a knife grabbed from a restaurant and police shot him" and the man fell to the ground.

Here's a video that appears to show the knife-wielding man on the ground after being shot by a police officer.

One Twitter user said, “just see this pic - Not mine - but IF that is a knife attacker/terrorist/murderer and the police have had to react and neutralise the threat, lets hope it was before too many got hurt.”
