A picture taken at the scene of a suspected terror incident near Parliament shows the moment an assailant is contained by armed police officers.
The suspected attacker crashed his car into pedestrians on Westminster Bridge before stabbing a police officer at the Houses of Parliament.
Eyewitness Frances, who was in the area when the incident happened, told ITV News reporter Emma Murphy that her partner was in parliament.
She said everyone in Parliament is still locked in, and said her partner had been in touch: "He understood that there'd been an incident on Westminster Bridge, and that a police officer had been stabbed.
"He texted to say that he's still in there and they won't let them out, and there's a suspected package in a car, so at the moment, I'm just going to wait for him to come out.
"I don't know how long he's going to be, but it's obviously very important for them to secure the area before they let them out."
