An extra 50 police officers a day will be on duty over the holiday weekend, it was announced yesterday.

Acting Superintendent Tracy Adams said the officers will be deployed to support Bermuda Day activities and the associated night-time celebrations.

Mr Adams warned: “Acts of antisocial behaviour will not be tolerated.”

Officers will carry out patrols and checks across the island and roadside breath-test checkpoints will in operation from tomorrow until Sunday.

The breath test checkpoints will be in Hamilton Parish, Devonshire, Pembroke, Paget, Warwick and Southampton.

Mr Adams added that some roads will be closed on Friday from 8.30am for the Bermuda Day Parade, the half-marathon and the Bermuda Bicycle Association’s Sinclair Packwood Memorial Race.

The Bermuda Half Marathon Derby and the bike race will start in St George’s and finish in Hamilton.

Mr Adams also advised people who planned to travel overseas to be at the airport by 8am to avoid delays. He added the marine police presence will also be increased as the weekend marks the traditional start of the boating season.

Mr Adams warned boaters to exercise caution around other vessels and to be on the lookout for swimmers.

He added: “Speed is an issue not only in maritime collisions, but it also creates a general nuisance that affects boaters at anchor near the shoreline. To that end, the five knot, no-wake zones will be strictly enforced.”

Mr Adams also asked people not to mix alcohol and boat use.

Mr Adams said members of the public should “exercise patience, tolerance and caution” so everyone could have a safe and enjoyable weekend.

He added: “We encourage members of the communities that they live in to work together to keep the peace in the neighbourhood in an effort to avoid the involvement of the police.”
