Taylor Swift Wembley concerts with help from security forces for counter-terrorism

When Taylor Swift returns to the stage, London authorities and Wembley Stadium will be taking extraordinary security measures – including some specifically deployed to stop potential terrorists… TMZ has learned.

Law enforcement sources tell TMZ… Taylor’s three upcoming shows at Wembley will rely on additional private security specializing in counter-terrorism, partly in response to the Vienna terror plot that was foiled by American and Austrian officials.

We’re told that private security forces will also be deployed due to the ongoing riots in London that are putting a huge strain on local police.

Our sources say that Wembley in particular has overall high-level security measures in place, especially compared to similar venues, and is one of the safest in Europe from a counter-terrorism perspective… but there are still concerns.

Our sources say the big issue for Taylor’s upcoming Wembley shows will be protecting the crowds of Swifties that always gather outside her concert halls.

We’ve already seen huge crowds outside her other European concert venues, like the one in Munich for example. The fact is that her rabid, loyal fans gather outside venues even if they don’t have tickets, and they also need protection.

Ben Knoopoperations director at FGH Security in England, tells TMZ … private security companies work with police outside events where fans gather, and they are usually tasked with tracking down suspicious people.

He says counter-terrorism security forces tend to deploy plainclothes and uniformed personnel, whose job is to spot strange people in the crowd. If someone scans the area for cameras and police, that would be a sign that something is wrong and security is closing in.

In most cases, we are told that the tactic is to be friendly to the suspicious person and ask if he or she needs help with anything. But if security notices even the slightest suspicion of something nefarious, the police are called immediately.

Increased security and emphasis on counter-terrorism measures follow this Taylor’s canceled concerts in Vienna… true 3 suspects have been arrested for alleged plans to detonate explosives at Taylor’s show and cause mass casualties among fans outside the venue.

Officially, the London Metropolitan Police says: “There is no indication that the cases being investigated by the Austrian authorities will have an impact on upcoming events here in London.”
