London terror attack lasted just 82 SECONDS before Khalid Masood was shot dead, CCTV analysis reveals

THE Westminster terror attack lasted just 82 seconds before Khalid Masood was shot dead.

Frame-by-frame examination of CCTV footage by police revealed the astonishing speed at which Masood, 52, caused carnage — killing four people and wounding more than 50.

Masood’s outrage began at precisely 40 minutes and eight seconds past two on Wednesday afternoon when he mounted a pavement on the south side of Westminster Bridge.

For the next 30 seconds his hired grey Hyundai 4x4 knocked pedestrians down like skittles — killing three — as he drove at an estimated 50mph.

At 2.40 and 38 secs the 4x4 crashed into the peri-meter fence of Parliament.

At 2.40 and 51 secs Masood emerged from the vehicle holding two knives.

Two seconds later the first 999 call was received by the Met Police.

Masood ran 50 yards round the corner and into the grounds of Parliament where he was confronted by PC Keith Palmer and a colleague.

The maniac shrugged off the colleague and then dived on PC Palmer, 48, as he fell against a barrier and to the ground.

A source revealed: “Keith slipped on the cobblestones which were wet after it had rained.

“He had his stab-proof vest on but Masood dived on him and stabbed him in the neck and armpit which were still exposed.”

Moments later at 2.41 and 30 secs the knifeman ran towards a police firearms officer who shot him.

The source said: “The officer was incredibly cool and withdrew his gun and slotted him, otherwise who knows what else might have happened?”

Met Police Deputy Assistant Commissioner Neil Basu said: “We still believe that Masood acted alone.”

But he added: “There is a possibility we will never understand why he did this. That understanding may have died with him.”
