Were there "security drills" same day as Manchester Attack?

I saw someone reference "Terrorist security drills" the same day as the actual attack. I did a google and could only find a 2016 security drill.

For anyone wondering why this matters, it seems there are "security drills" for every major terrorist event that coincide with the day an actual attack happens.
