The bombing of the Ariana Grande concert in Manchester killed 22 people, which has led to an increase in police presence at nightclubs, concert halls and festivals in the U.K.
Humberside, South Wales and the Metropolitan police forces were present when it was announced that increased security measures would be used for a variety of events to come.
Promoters expressed sympathy for the victims of the bombing at the Ariana Grande concert and committed to making safety a top priority.

The Met spearheads counterterrorism efforts across the country, and it has designated the deployment of armed officers throughout the capital a mission termed Operation Hercules.
Its purpose is reportedly to "make London as hostile an environment as possible for any would-be attacker."
Officers are likely to guard lots of the events on the smaller scale where police protection would not have initially been in place, according to the Met whose office added that it was corresponding with promoters to make sure that information was mutual and protective security was available for their events.
"Here in London, we are determined to do all we can to protect the capital. That means that over the coming days as you go to a music venue, go shopping, travel to work or head off to the fantastic sporting events you will see more officers—including armed officers," said Met Commander Jane Connors.
Humberside police those intending to attend the Radio 1 Big Weekend in Hull on Saturday can expect stringent security checks.
