Officers from the Met Police have promised there will be minimal difference in security at the Wimbledon tennis championships this year compared with previous tournaments.
The Met asked tennis fans attending the tournament to "stay alert but not alarmed" as they heighten security in light of recent terror attacks on sporting events.
From Saturday: 'Stay alert but not alarmed' says Met as force takes to Twitter to police Wimbledon tennis championships
Temporary Commander Nick Downing said: "It is a minimal difference to last year, I must stress that we have had firearms officers deployed before but they will be far more visible this year.
"We want to minimise disruption to residents and the community as well.
"We are constantly reviewing our plans."
T.Comm Downing said events such as what happened in Orlando feed into their approach to major events like the Wimbledon championships.
He urged spectators at the event to bring any suspicious behaviour to the attention of police as soon as possible.
T.Comm Downing said: "Keep your belongings with you, and zip up bags to keep them from opportunistic thieves.
"Our other message is around ticket touts, do not go near them, buy from the club or from authorised online sellers.
"We work closely with the All England club and have built up a relationship over many years.
"Our aim is to make everyone feel happy, safe and secure and to hopefully see a British winner."
Chief Superintendent Colin Morgan said last week that the officers would make full use of Twitter to send out updates during the two-week event.
Wimbledon Championships start today with the men's final on July 10 and woman's final the day before on July 9.
